BEFS Data Reduction and Analysis

BEFS data consists of spectroscopic data in FITS format. The FITS spectra contain binary table extensions with both 1st and 2nd order spectra. Please see:

   Reading in IDL   for information on reading BEFS data with IDL.
   Reading in IRAF   for information on reading BEFS data with IRAF, and please see
   Data Caveats   for details about nuances in the data.

Time-tagged spectral-photon lists for any spectrum can be produced using the extract-tt routine. See the Time-Tagged Data page for more information. The extract-tt routine (and other project-provided data analysis software) can be downloaded from the archive.stsci.edu/pub/orfeus/befs/software directory via the web or anonymous ftp.
