Spectral Data Coplot Utility

Enter up to 15 data set names (e.g., SWP16877,O45P021B0,...) below to coplot spectra from STIS, IUE, EUVE, HUT, BEFS, TUES, FOS, GHRS, or WUPPE. KEPLER light curves (e.g., kplr007686127-2009131105131_llc) can also be specified. Scale factors and X-axis range can be specified either here or on the displayed plot page. (Caution: the averaging feature checks that the input spectra have the same total number of points and averages them bin by bin. It will cheerfully 'average' spectra with different wavelength ranges or resolution, producing meaningless output.)
