This class represents the calfile used in the astrometric calibration
of the science images.
The details of the steps performed in the derive_astrometry() method
which derives the formal astrometric solution with LDAC are as
follows:
Steps: Sextractor.sex - creates original catalog from source
frame
LDAC.ldacconv - converts SExtractor catalog to cat_name
LDAC.preastrom - determines linear affine parameters and
creates USNO catalog to be associated
LDAC.aplastrom - applies affine prameters from AFFINE
table created by preastrom
LDAC.filter - filters out most non-stellar-like
sources from OBJECTS table
LDAC.associate - associates modified catalog from
aplastrom after preatrom to the USNO
catlog output from preatrom
LDAC.make_ssc - makes a pairs catalog from individual
catalogs output from associate
LDAC.astrom - runs the astrometric solution on the
unmodified catalog output from
preastrom using the pairs catalog
output from make_ssc
LDAC.aplastrom - applies the OBJECTS table of the
astrom output catalog with the values
from the ASTROM table added by astrom

The applied solution is represented by a catalog extracted from
a RegriddedFrame created by applying the astrometric solution to
the source ReducedScienceFrame. The derived (predicted) solution
can be represented in one of three ways:
1. the catalog that the solution parameters are derived from as
created by LDAC during the AstrometricParameters make (requires
that the make was just run in the same directory so the catalog
is available)
2. a catalog extracted from the source ReducedScienceFrame using
the astrometric solution parameters stored in the
AstrometricParameters object
3. a catalog extracted from the source ReducedScienceFrame using
the original parameters stored in the frame header with the
astrometric solution parameters stored in the
AstrometricParameters object applied by LDAC
The selection of the type of the derived catalog used in the
comparison is done with the 'derived_type' parameter and is one of
'solution', 'sextractor', or 'ldac' and are related to the above
methods in the following way:
solution: use catalog from method 1.
sextractor: use catalog from method 2.

By default, all plots are saved as PNG (.png) for later inspection.
To change this behavior, set plot_params.EXTENSION to another format
(.ps, .eps, etc.) or to None to save nothing.

The applied solution is represented by a catalog extracted from
a RegriddedFrame created by applying the astrometric solution to
the source ReducedScienceFrame. The derived (predicted) solution
can be represented in one of two ways:
1. the catalog that the solution parameters are derived from as
created by LDAC during the AstrometricParameters make (requires
that the make was just run in the same directory so the catalog
is available)
2. a catalog extracted from the source ReducedScienceFrame using

The selection of the type of the derived catalog used in the
comparison is done with the 'derived_type' parameter and is one of
'solution' or 'sextractor' and are related to the above methods in
the following way:

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)

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

class AstrometricParametersParameters(common.database.DBMain.DBObject) |
| |
Processing parameters for AstrometricParameters
Procecessing parameters determine how the object is to be created
and the quality control (QC) limits for the newly created object.

- MAX_RMS_OVERLAP
- QC: Maximum internal RMS of overlap residuals [arcsec]
- MAX_SIGMA
- QC: Maximum value of SIG_DRA or SIG_DDEC [arcsec]

- QC: Maximum value of SIG_DRA or SIG_DDEC for overlaps [arcsec]
- MIN_NREF
- QC: Minimum number of reference star pairs [None]
- MIN_N_OVERLAP
- QC: Minimum number of overlap star pairs [None]
- SOURCE_CODE_VERSION
- The version of the source code [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.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.
- commit(self)
- Commits object including objects that are referenced and have been changed.
If this object refers to other persistent object a commit() ensures that
1. ALL changes to the object and referred objects are made persistent.
2. NONE of the changed object and referred objects are made persistent.
Under normal circumstances only the first thing should ever happen.
If the second case occurs it is almost certainly because of some bug in
the routine that implements the DBProxy interface.
- 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.
Class methods inherited from common.database.DBMain.DBObject:
- get_inverse_properties(cls, props=None) from common.database.DBMeta.DBObjectMeta
