29 data_condition_flag_65 smallint A 16-bit flag per band indicating various data condition. In version 1 catalogue three bits are used. The first bit (bit0) is used to indicate the CDS sampling mode. The second bit (bit1) warns the flux of the band is less than a half of the detection limit, and is not reliable. The fourth bit (bit3) tells that the source is possibly false detection due to `side-lobe' effects (see, Section 7.7 of the Release Note). The third bit (bit2) was previously indicated an anomaly which does not exist in the current version, and thus is kept unused. Sources with bit1 or bit3 = 1 have flux_quality_65 = 2 or less. Other bits are reserved for the future implementation.

41 month_confirmation_flag_65 smallint The month confirmation flags are prepared per band. The value is 1 when the source is observed in the scans separated more than one months (usually an object is visible at every 6 months). This information is independent to hours confirmation and can be 1 even if the source is not confirmed (flux_quality_65 = 1).
