*t2d* -- FITS tape to disk for files with binary tables

To read data from your ROSAT tape use the task t2d. Make sure you are in a directory with 10 Mbytes of space. If your data are in RDF format there will be 13 PSPC FITS files (8 HRI). If your data are in US Rev0 format, or is from the Rev0 archive there will be more FITS files.

Tape handling is site-dependent. Users at SAO should refer to the SAO-HEAD IRAF Users Site Guide for details concerning tape access. Assuming the user is set up so that a tape drive is available and accessible:

  
  To mount 9 track tapes at SAO:

    cfa#: rsh reel                                   # remote logon to reel
    cfa250: getdev mtq                             # assign tape drive mtq.
                        # The other choices are posted on the input drives.
    cfa250: cd iraf                   # Enter directory with login.cl file.

  cfa#: cl 
  cl> allocate mtq                 # IRAF allocation (this specific to SAO)
  device mtq is already allocated              # ignore this message, it is
                                                         # allocated to you
  
  
  cl> dataio

  da> t2d
  
  Input file descriptor: mtq
  List of files:                             # carriage return (for all files)
  Output file root name:  rostape

To conserve on disk space you can load only selected files from the tape.

US Rev0 FITS files used by PROS analysis are ``2-12,14,25" for PSPC (HRI ``2-6,8"). See the ROSAT Data Products Guide for file descriptions.

RDF FITS files are packaged in a smaller number of FITS files with multiple extensions in each file, see explain_xdata for a description; the tape list follows:
