ImCat is a powerful and user-friendly image and catalogue manipulation software. It was originally developed for faint galaxy photometry in weak lensing studies and provides a comprehensive set of tools for this purpose. ImCat is composed of a set of standalone unix commands which can be invoked from the shell, shell scripts, or perl scripts.
ImCat is a great and easy-to-use image and catalogue manipulation software. The imcat tools are arranged into sections. Use ’man sectionname’ to list the tools available in a section. The ’imcat’ software was developed initially to do faint galaxy photometry
for weak lensing studies, and provides a fairly complete set of tools
for this kind of work. Unlike most packages for doing data analysis,
the tools here are provided as a set of standalone unix commands which
you can invoke from the shell, via shell scripts or from perl scripts
as you think appropriate. You don’t have to learn a new shell syntax
- just use whatever you are most comfortable with - and you can just
use whatever bits you want. The imcat libraries are not shared, so
you can just download a single executable if you like. The standard
unix and pgplot libraries are shared, and you may need to explicitly
locate them via the LD LIBRARY PATH env variable. All of the commands
have a "man-page". The html versions here tend to be out of date,
but the most definitive version for any command can always be obtained
by issuing the command with the ’-u’ (for usage) flag. Of course,
there is no guarantee that these are perfectly accurate - as a last
resort simply peruse the c-code.
