4.1.1 The EPIC Observation Data Files

The ODF names for the EPIC data will look something like:

• mmmm_iiiiiijjkk_aabeeeccfff.zzz, where
  • mmmm: revolution number
  • iiiiiijjkk: observation number
  • aa: detector ID (M1 - MOS1, M2 - MOS2, PN - pn)
  • b: flag for scheduled (S), unscheduled (U) observations, or (X) for general use files
  • eee: exposure number within the observation
  • cc: CCD identifier
  • fff: data identifier (see Table 3)
  • zzz: Format (FITS - FIT, ASCII - ASC)

Table 3: ODF data file identifiers relevant for EPIC analysis.
