/software/stsdas/refdata/README The subdirectories beneath this one contain various Reference Data obtained for use to calibrate HST. The following is a description of the Data: README This file. flux_stds This directory contains data for flux standards used to calibrate HST. These files contain data from 500A to 12000A, with real data from sources such as J.B. Oke, IUE, Voyager, etc., and model data spliced into areas where no data was available. oke_data This directory contains data delivered by J.B. Oke to the Institute for calibration of HST. Most data is from 3200A to 9000A, with flux in AB mags. This data was published in the Astronomical Journal (99, 1990, p.1621). synphot This directory contains the Instrument Throughput files, graph and componemt tables, and stellar model data required to use synphot package in STSDAS.
