Details of the observation and exposures (11 columns)

OBS_ID (10A): The XMM-Newton observation identification.
REVOLUT (4A) [orbit]: The XMM-Newton revolution number.
MJD_START (D) [d]: Modified Julian Date (i.e., JD - 2400000.5) of the start of the observation.
MJD_STOP (D) [d]: Modified Julian Date (i.e., JD - 2400000.5) of the end of the observation.
OBS_CLASS (J): Quality classification of the whole observation based on the area flagged as bad in the manual flagging process as compared to the whole detection area, see Sec. 3.2.6. 0 means nothing has been flagged; 1 indicates that 0% < area < 0.1% of the total detection mask has been flagged; 2 indicates that 0.1% <= area < 1% has been flagged; 3 indicates that 1% <= area < 10% has been flagged; 4 indicates that 10% <= area < 100% has been flagged; and 5 means that the whole field was flagged as bad.
This column replaces OBS_FLAG used in 2XMMp.
PN_FILTER (6A): PN filter. The options are Thick, Medium, Thin1, Thin2, and Open, depending on the efficiency of the optical blocking. (For a detailed description see 3.3.6 EPIC filters and effective area on http://xmm.esac.esa.int/external/xmm_user_support/documentation/uhb).
M1_FILTER (6A): M1 filter. The options are Thick, Medium, Thin1, and Open, depending on the efficiency of the optical blocking, (For a detailed description see 3.3.6 EPIC filters and effective area on http://xmm.esac.esa.int/external/xmm_user_support/documentation/uhb).
M2_FILTER (6A): M2 filter. The options are Thick, Medium, Thin1, and Open, depending on the efficiency of the optical blocking, (For a detailed description see 3.3.6 EPIC filters and effective area on http://xmm.esac.esa.int/external/xmm_user_support/documentation/uhb).
PN_SUBMODE (23A): PN observing mode. The options are full frame mode with the full FOV exposed (in two sub-modes), and large window mode with only parts of the FOV exposed, see Tab. 2.3. For a detailed description see 3.3.2 Science modes of the EPIC cameras on http://xmm.esac.esa.int/external/xmm_user_support/documentation/uhb.
M1_SUBMODE (16A): M1 observing mode. The options are full frame mode with the full FOV exposed, partial window mode with only parts of the central CCD exposed (in different sub-modes, see Tab. 2.3), and timing mode where the central CCD was not exposed ('Fast Uncompressed'). For a detailed description see 3.3.2 Science modes of the EPIC cameras on http://xmm.esac.esa.int/external/xmm_user_support/documentation/uhb.
M2_SUBMODE (16A): M2 observing mode. The options are full frame mode with the full FOV exposed, partial window mode with only parts of the central CCD exposed (in different sub-modes, see Tab. 2.3), and timing mode where the central CCD was not exposed ('Fast Uncompressed').
