1. Identifies the record as an Exposure Record.
2. A sequential counter of the exposures for that instrument.
3. All comments will have the syntax ' / text'.
4. Y/N flag indicating whether the exposure was scheduled or not. An 'N' will indicate that the exposure was not scheduled and resulted from a change request.
5. The type of the exposure ('SCIENCE'/ 'CALIBRATION') . The field will indicate whether the exposure is a science exposure requested by the GO or a calibration exposure inserted by SOC personnel
6. The mission planning exposure identifier
7. The syntax is ppppppoolliieee (Section ).
8. UTC time with the format yyyy-mm-ddThh:mm:ss.
9. The scheduled start and end time of the exposure assigned during scheduling.
10. The start and end time of the exposure as calculated by the XSCS (see description of DATE-OBS and DATE-END in Section and elsewhere).
