Abstract

Authors DJM, RFW, and EC have accumulated about 1000 spectra of cool stars from CTIO, ESO, and LCO over the interval 1985 to 1994 and processed them with the standard IRAF tasks into FITS files of normalized intensity vs. wavelength. With the growth of the Web as a means of exchanging and preserving scientific information, we desired to put the spectra into a Web-readable format. We have searched without success sites such as the Goddard FITS Image Viewer page, http://fits.gsfc.nasa.gov/fits_viewer.html</u>, for a program to convert a large number of 1-d stellar spectra from FITS format into common formats such as PDF, PS, or PNG. Author APP has written a Python script to do this using the PyFITS module and plotting routines from Pylab. The program determines the wavelength calibration using header keywords and creates PNG plots with a legend read from a CSV file that may contain the star name, position, spectral type, etc. It could readily be adapted to perform almost any kind of simple batch processing of astronomical data. The program may be obtained from the first author (jack@stsci.edu).

Support for DJM from the research program for CSC astronomers at STScI is gratefully acknowledged. The Space Telescope Science Institute is operated by the Association of Universities for Research in Astronomy Inc. under NASA contract NAS 5-26555.
