ODF Data

ODF data come with file names in the following format:

• mmmm_iiiiiijjkk_aabeeeccfff.zzz

  mmmm - revolution orbit number

  iiiiii - proposal number

  jj - target ID number in proposal

  kk - exposure number for target

  (NOTE: The ten-digit combination of iiiiiijjkk is the observation number and is used repetitively throughout the file nomenclature.)

  aa - detector (M1 - MOS1, M2 - MOS2, PN - PN, OM - OM, R1 - RGS1, R2 - RGS2, SC - spacecraft)

  b - flag for scheduled (S) or unscheduled (U) observations, or X for general purpose files)

  eee - exposure number

  cc - CCD number or OM window number

  fff - data identifier for the three detectors or spacecraft itself; see Table 5.1.

  zzz - format (FIT - FITS, ASC - ASCII)
