libcfitsio.a

is the library of CFITSIO (C) functions used to compile some FORTRAN programs that input/output FITS files. It is free software downloadable with more information from the following website: http://heasarc.gsfc.nasa.gov/docs/software/fitsio/fitsio.html

imgets

is a FORTRAN program that returns the value of a header card from a FITS image.

rctred

is a FORTRAN program that does basic image reduction tasks on a group of images. It takes as its input a parameters file detailing which operations will be performed and two files listing the names of images to be input and output. The parameters file can be created using the companion script setred.

setred

is a Perl script useful to create the input parameter list for rctred.

rctcom.pl

and rctcom.cl rctcom.pl is a Perl script used to combine a list of images. It takes as its input a parameters file detailing which operations will be performed and a file listing the names of the images to be combined. This (short, user-interface) script then calls on an IRAF shell script, rctcom.cl, which completes the actual operations. The parameters file is best created using the companion script setcom.

rctcom.f

is a Fortran alternative to the rctcom.pl and rctcom.cl scripts. It is designed to be operated in the same way and produce the same results. The fortran program is useful if the IRAF script fails to work (as may be the case for some new versions of linux!).

rctcom

can either be a symbolic link pointing to rctcom.pl or the executable created by compiling rctcom.f. This way, any invocation of rctcom will execute the user's choice of software (IRAF or Fortran).

setcom

is a Perl script useful to create the input parameter list for rctcom.

rcthedit

is a FORTRAN program used to edit, add, and delete header keywords from a FITS image.

rctnight

is a Perl script designed to do basic image reductions on a night's worth of data. It can be used to first reduce and combine calibration data images (flats and biases) and then apply these to combine and reduce a number of object images. It will attempt to group together the images having the same properties and to apply the proper calibration data to these images. It takes a parameter file as its input, which can be created or edited using the companion script setnight. Rctnight can be operated in an interactive or automated manner and writes a logfile describing the steps it takes.

setnight

is a Perl script useful to create the input parameter list for rctnight.
