The immatch package contains a set of routines for registering, matching
the
point spread functions, and matching the intensity scales of two or
more
images using a variety of techniques. The majority of these tasks are
new
and are being made available in order to invite user testing and comments
prior to distribution as part of the IRAF core system. A few of the
tasks
are modified versions of tasks already in the system. These modifications
were necessary to properly support the new tasks. The immatch package
is very much a work in progress and new tasks will be added in the
future.
The current contents of the package are:
ccmap -- Compute image plate solutions using celestial coordinate lists
cctran -- Transform from x-y to ra-dec and vice versa using plate solutions
ccsetwcs -- Create an image wcs from the plate solution
geomap -- Compute geometric transforms using matched x-y lists
geotran -- Geometrically transform a list of 1-D or 2-D images
geoxytran -- Geometrically transform a list of x-y coordinate lists
linmatch -- Match the linear intensity scales of 1-D abd 2-D images
linxymatch -- Generate matched x-y lists using coordinate lists
psfmatch -- Match the point-spread functions of 1-D and 2-D images
slalib -- Starlink positional astronomy library
skyctran -- Transform lists from one celestial coordinate system to another
skymap -- Compute geometric transforms using image celestial coordinates
skyxymatch -- Generate matched x-y lists using image celestial coordinates
sregister -- Register 1-D or 2-D images using image celestial coordinates
wcscopy -- Copy the wcs of one image to that of another
wcsctran -- Transform between iraf wcs using image wcs information
wcsmap -- Compute geometric transforms using image wcs information
wcsxymatch -- Generate matched x-y lists using image wcs information
wregister -- Register 1-D or 2-D images using image wcs information
xregister -- Register 1-D or 2-D images using x-correlation techniques
