With the advent of RDF, the output from qpspec (for most instruments) has been divided into three tables:
| _obs.tab | counts |
| _soh.tab | source off-axis histogram |
| _boh.tab | background off-axis histogram |
Tasks downspecrdf, and upspecrdf translate between RDF and pre-RDF formats. upspecrdf will be useful to re-analyze previously extracted spectral data; downspecrdf is currently necessary for use with proscon (version 2.2), the translation program for input into xspec, which does not work with RDF data.
input files: rp90_obs.tab, rp90_soh.tab, rp90_boh.tab
output file: rp90_prdf_obs.tab
