Contributed Data Analysis Software

  • correct_astro.zip - This file contains an IDL program and auxiliary data sets produced by Derck Massa and Ed Fitzpatrick for recalibrating IUE NEWSIPS low dispersion data using HST FOS standards. The software and analysis is described in the paper "A Recalibration of IUE NEWSIPS Low-Dispersion Data'', Massa, D., Fitzpatrick, E.L. 2000 ApJS, 126, 517 ( 2000ApJS..126..517M). Note the IDL program requires routines available from the IDL Astronomy User's Library.
