- Method resolution order:
- PhotRefCatalog
- astro.main.BaseCatalog.BaseCatalog
- common.database.DataObject.DataObject
- common.database.DBMain.DBObject
- __builtin__.object
- astro.main.OnTheFly.OnTheFly
Methods defined here:
- __init__(self, pathname='')
- associate(self, incat, outcat, ra_range=[], dec_range=[])
- This method is used to associate the input SExtractor catalog
("incat") with the standard star catalog. The resulting catalog is
"outcat".
- dump(self, dump_file='cal569E_dump.txt')
- This method dumps the content of the catalog into an ASCII-file.
- get_dict_of_magnitudes(self, mag_id, index_list=[])
- This method returns a dictionary that contains the magnitudes of the
sources in the catalog for the requested photometric band. If an
index_list is given, only for the stars in this index_list the
magnitudes are returned.
Examples of use : get_dict_of_magnitudes('SloanR')
get_dict_of_magnitudes('JohnsonV',
index_list = [1, 2, 3])
- get_dict_of_origins(self, index_list=[])
- get_list_of_bands(self)
- get_number_of_sources(self)
- get_source_attributes(self)
- get_source_data(self, columns, index_list=[])
- make_skycat(self)
- This method creates a dump of the reference catalog that can be used
to overplot images in skycat.
Class methods defined here:
- exist(cls, **args) from common.database.DBMeta.DBObjectMeta
- Search for PhotRefCatalog for on-the-fly parameters.
Static methods defined here:
- get()
- This static method is used to retrieve a PhotRefCatalog object from
the database.
Data descriptors defined here:
- creation_date
- Date this object was created [None]
- filename
- The name of the associated file [None]
- globalname
- The name used to store and retrieve file to and from Storage [None]
- object_id
- The object identifier
The object identifier is an attribute shared by all persistent
instances. It is the prime key, by which object identity is established
Methods inherited from common.database.DataObject.DataObject:
- FileName(self)
- Return the pathame of the object
- Name(self)
- Return the name of the object
- check_mandatory_dependencies(self)
- check if all the mandatory dependencies are set
- commit(self)
- derive_hash(self)
- Apply hashing function to the contents of the file that is part of
this object.
The SHA hashing function is used to calculate a hash value of the
contents of this DataObject. The hash value is returned as a
hexadecimal string.
- distinct(self, param_list)
- This method returns the distinct values from an input list. The
current implementation is kinda cheesy.
- exists(self)
- Test is the file existsts
- get_canonical_name(self, processlevel='')
- The canonical name of a DataObject.
- get_pathname(self)
- Getter for pathname
- is_on_dataserver(self)
- Checks if file is accessable on the dataserver.
NOTE: A return of False does NOT imply the file is not on any
dataserver! It is simply not on any accessable
dataserver.
- is_stored(self)
- locate(self)
- See common/net/dataserver_client.py (Data_IO.locate).
Returns a list of strings describing all dataservers where the file is
located as well as a few properties of the file, i.e.
['ip=...,port=...,path=...,size=...,mdate=...,
'ip=...,port=...,path=?,size=?,mdate=?']
Question marks indicate that this dataserver is not reachable.
- name_insert_suffix(self, suffix)
- name_replace_suffix(self, suffix)
- name_with_new_suffix(self, suffix)
- release(self)
- retrieve(self)
- set_filename(self, pathname=None, processlevel='')
- Specify a filename for this DataObject or use the default filename.
This method is used to set the filename attribute of a DataObject.
If called without a filename, the filename is set to the canonical name.
Classes that are derived from DataObject are expected to define a
method get_canonical_name() that returns the name for an instance
of that class. This is mandatory for CalFiles (or files that are
store()d on the data server) and optional for other files.
- set_pathname(self, pathname)
- Setter for pathname
- set_process_parameters_from_dict(self, pars={})
- pars is a dictionary of the type e.g.:
{'BiasFrame.process_params.SIGMA_CLIP':8}
- set_stored(self)
- set_user_config(self, pars={})
- store(self)
- store_with_hash_as_name(self, prefix='', suffix='fits')
- Name the file after the hash value of the file and store it.
First the hash value of the file is calculated. The pathname of the
dataobject is renamed to the hash value with the given suffix appended.
Then the file is stored.
Class methods inherited from common.database.DataObject.DataObject:
- is_cal(cls) from common.database.DBMeta.DBObjectMeta
- Test for being cal, derived raw classes should set _IS_CAL to 1
- is_config(cls) from common.database.DBMeta.DBObjectMeta
- Test for being config, derived raw classes should set _IS_CONFIG to 1
- is_raw(cls) from common.database.DBMeta.DBObjectMeta
- Test for being raw, derived raw classes should set _IS_RAW to 1
- is_science(cls) from common.database.DBMeta.DBObjectMeta
- Test for being science, derived raw classes should set _IS_SCIENCE to 1
- is_seq(cls) from common.database.DBMeta.DBObjectMeta
- Test for being seq, derived raw classes should set _IS_SEQ to 1
- is_support(cls) from common.database.DBMeta.DBObjectMeta
- Test for being config, derived raw classes should set _IS_SUPPORT to 1
Data descriptors inherited from common.database.DataObject.DataObject:
- pathname
Data and other attributes inherited from common.database.DataObject.DataObject:
- filepath = './'
- localname = ''
- mandatory_dependencies = ()
- storage = <common.net.dataserver_client.Storage at 0xe27ef0>
Methods inherited from common.database.DBMain.DBObject:
- __del__(self)
- Destructor for the DBObject
This destructor is called by the garbage collector for the transient
part of the DBObject. When it is called it calls the gc_transient()
method of the DBProxy implementation. The implementation of the
gc_transient() method can then decide what to do with the persistent
counterpart.
E.g. the database can be synchronized with its transient counterpart.
Another possibility is that the gc_transient() implementation checks
whether any attributes of a read-only object have changed since an
object was fetched from the database. If there are differences an
exception can be raised.
- __reduce__(self)
- Method necessary to create picklable objects
This mehod return a tuple containg a function object used for
unpickling and a picklable state tuple, to be used as argument
to the unpickle function. If necessary this object is registered
in the pickle cache
- as_dict(self, seqnr=1, dependency_name='', dictionary={}, allow_lazy_typed_list=False)
- Method much like the info method, but returns a dictionary.
Dictionary looks like:
{'<classname>.<property1_name>.<property2_name>': value,
'<classname>.<property2_name>.<property3_name>': value}
Problem: infinite loops for cold/flat dependencies. It seems a maximum
recursion depth limits the problem.
- get_creator(self)
- Returns the name of the user who created this object.
- get_persistent(self)
- get_project(self)
- Returns the name of the project to which this object belongs.
- info(self, level=0, doc=False, _indent=0, _printclass=True)
- Print the values of all persistent properties of the object.
level : level of introspection
doc : display docstrings for attributes
_indent : internal parameter used for formatting
_printclass : internal parameter used for formatting
- inverse_objects(self, max_results=100)
- Iterate through and return all objects that use the current object
max_results The maximum number of objects returned per query
- inverse_query(self)
- go through all inverse properties to see if this object is used
- persists(self)
- Returns whether an object is already made persistent or transient.
- recommit(self)
- Commits changes to an object, without following links.

Provides:
__new__ -- manages class construction
__call__ -- manages object instantiation
- database = <common.database.DBOracle.DBProxy instance at 0x12fb7e8>
- pickle_id = None
Methods inherited from astro.main.OnTheFly.OnTheFly:
- Flagged(self)
- Check if any flag is set
return 1 for flag is set
return 0 no flag
- after_do_make(self, switches=None)
- extra make statements, this method can be overridden by OnTheFly classes to
implement extra make statements which will be executed after the make of self
- after_set_onthefly_dependencies(self, switches, advanced)
- this method is called after the onthefly method set_onthefly_dependencies
derived classes can implement this method to customize the dependencies
setting after this has been done automatically by onthefly
- after_uptodate_object(self, dependencies_missing, dependencies_new, dependencies_obsolete)
- The uptodate_object method determines if the object is uptodate, and will result in three listings :
dependencies_missing - missing mandatory dependencies
dependencies_new - new dependencies
dependencies_obsolete - current dependencies that are obsolete
Derived classes can override this method to tweak the listings
- check_for_mandatory(self, dep_str, dep_new)
- check if dependency is mandatory and present
dep_str is the name of the attribute, dep_new is the (attribute) object
- get_onthefly_dependencies(self, advanced=None)
- Method retrieves a list of all dependencies used for
on-the-fly processing
Return: [dependency, dependency class, dependency name]
- uptodate(self, date_time=None, template=None, switches=None, advanced=None)
- This method checks if the object is up-to-date, for the given datetime.
OnTheFly_uptodate class has the functionality for checking uptodate
Class methods inherited from astro.main.OnTheFly.OnTheFly:
- get_onthefly(cls, date_time=None, filter=None, chip=None, object_id=None, advanced=None, switches=None, template=None, parent=None, parent_attr=None) from common.database.DBMeta.DBObjectMeta
- For the given parameters and class get the object,
if the object does not exist -> make it.
This is done recursively for all dependencies.
The object can only be made if there are raws

| |
This class describes a single reference source used for the photometric
calibration.
