LSTfloatLocal Sidereal Time at start of the exposure in seconds elapsed since sidereal midnight. The comment includes a civil representation of the value.s
MJD_OBSfloatModified Julian Day of the start of the exposure. The MJD is related to the Julian Day (JD) via the formula: MJD = JD-2400000.5 The comment includes a civil representation of the date and time. 8 decimals are required for a precision of one millisecond, 5 decimals for a precision of one second.d
nifuintThe IFU used to make the observation
object_idoidtypeThe object identifier

The object identifier is an attribute shared by all persistent
instances. It is the prime key, by which object identity is established
OBJECT_NAMEstrIdentification of target observed.
