This information includes the telescope pointing position (Actual, Demand and Base) in both the tracking system and AZEL coordinate frames, jiggle patterns, telescope row/offset index amongst others.

Additional derived columns are included in addition to those stored directly in the JCMTSTATE extension. All telescope values include a correction for motion of the secondary mirror.
RA/DEC
Tracking coordinates in degrees. The columns will have the same name even if the telescope was tracking in GALACTIC.
DRA/DDEC
Tracking offsets from the base position in arcsec.
AZ/EL
Azimuth and elevation in degrees. Calculated directly from JCMTSTATE without being converted to RA/Dec.
DAZ/DEL
Azimuth and elevation offsets from the base position in arcsec.
TELSPEED
Instantaneous telescope speed in arcsec/sec.
WVMTAU
Zenith 225 GHz opacity derived from the water vapor radiometer.
PWVZEN
Precipitable water vapor at the zenith in mm.
PWVLOS
Precipitable water vaport in the line of sight in mm.
Note that information from the ACSIS extension is not included at this time. This is partly because this extension can change in shape between observations. MCE header information is included for SCUBA-2 data files.
