5.5.1 Raw RGS Data Files in the ODF

Raw data of all seven XMM-Newton instruments, including RGS1 and RGS2, are to be found in a single directory /odf. If the delivery includes data from more than one observation, there will be a separate directory for each. The ODF names for RGS data are as follows:

• mmmm_iiiiiijjkk_aabeeeccfff.zzz, where
  • mmmm: revolution orbit number
  • iiiiiijjkk: observation number
  • aa: detector ID (R1 - RGS1, R2 - RGS2, SC - XMM-Newton spacecraft)
  • b: flag for scheduled (S) or unscheduled (U) observations, or (X) for general use files
  • eee: exposure number within the observation or "000"
  • cc: CCD identifier or "00"
  • fff: data identifier shown in Table 6
  • zzz: Format (FITS - FIT, ASCII - ASC)
