MOSASTROM
Name
mosastrom
Purpose (one Line Only)
Astrometry solution for multi-detector image sets
Description
Category
Astrometry
Calling Sequence
mosastrom,name,xoffset,yoffset,rotang
Inputs
name - String that defines the name of the image to process
xoffset - Vector, one element per image in the mosaic, that describes
the offset of each relative to the optical axis. The actual
definition is that this is the X position of the optical
axis in the native pixel coordinates of each image.
yoffset - Vector, one element per image in the mosaic, that describes
the offset of each relative to the optical axis. The actual
definition is that this is the Y position of the optical
axis in the native pixel coordinates of each image.
rotang - Rotation of each image relative to the anchor image. (radians)
Optional Input Parameters
Keyword Input Parameters
ANCHOR - Number of the image that is the anchor upon which the
monolithic coordinate system is to be based. The default
is the one whose (0,0) pixel is closest to the optical axis.
Note that this value is a number that points into the
input xoffset,yoffset arrays and starts at 0.
KEYLIST - Name of a file containing a correspondence list. This list
associates a set of standard names with the actual keyword
names found in a FITS file header. If this keyword is
omitted, a default list is used (see loadkeys.pro)
NEWTERMS - String array with the names of the terms to use in the fit.
Default=use the terms as found in the initial astrometric
solution.
NEWRENORM - This keyword allows you to change the renormalization
factor for the astrometric solution. The default is
to use the value that is found in fitcoeff.dat.
PATH - String, name of the directory where the images can be found.
Default=current directory
CATDIR - Sring, name of the directory where the catalog files can be found
default is the current directory
SRCDIR - String, name of the directory where the source files can be found
Default='Src' (relative to the current directory).
REFDIR - STring, name of the directory where the correlated star/catalog
lists are stored, Default='Refstars'
SUBARU - Flag, if set indicates that the file and naming scheme from
the Subaru Observatory is to be used (individual files for
each image in the mosaic). If this not set the default
file behavior is to look for a multi-group FITS file that
contains all images in one file.
IMACS - Flag, if set indicates that the file and naming schme from
the Magellan Observatory IMACS camera is to be used (individual
files for each image in the mosaic).
