• Time related attributes:
  • observation related: DATE_OBS and DURATION required by XMM-SOC-ICD-0006-SSC ([3]), write also DATE_END and OBSSTART, OBSSTOP
  • exposure related: DATE-OBS and DATE-END required by XMM-SOC-ICD-0004-SSD ([1]), write also EXPSTART, EXPSTOP
• SAS_VERBOSITY should be set to `Sparse' (4) for normal processing and `Verbose' (5) for more detailed processing. Values of 6 and higher may yield quite a number of messages related to rejected events (MIPs) depending on CCD number and instrument mode.
• SAS_MEMORY_MODEL should be set to `high' for normal processing.
• Information about possible errors in the ODF is needed to decide about additional criteria to flag wrong frames and events: can the ODF still be corrupted by transfer jumps, bit flips, etc. or are these checks done elsewhere?
