cspec is a program for working with spectra. It can open text files with columnar data or binary files in unifspec format. It was developed specifically for use on the HST Treasury Program on Eta Carinae for HST STIS data. It is general enough though that it can be used with any continuous data in the form y=f(x).

cspec can be used to view, print and analyze spectra. It currently supports equivalent width and full width at half-max (FWHM) calculations. Plots can be exported in JPEG, PNG or EPS format. It also support printing of plots.

cspec is written using GTK+ and should in theory work on any machine that can compile and run GTK+ applications. It has been tested on Linux and Sun Solaris.
