Primary HDU keywords

The OPC FITS keywords for the primary HDU conforms to the definition for common FITS headers as described in GBT Software Project Note 4.0 ``Device and Log FITS Files for the GBT.'' In fact, there are no additional keywords other than the keywords defined in GBT Software Project Note 4.0 ``Device and Log FITS Files for the GBT.''

The primary header keywords for the OPC FITS file are as follows:

SIMPLE  =                    T / file does conform to FITS standard
BITPIX  =                    8 / number of bits per pixel
NAXIS   =                    0 / number of data axes
EXTEND  =                    T / FITS dataset may contain extensions
ORIGIN  = 'NRAO Green Bank'    /
INSTRUME= 'Optical Pointing Camera' / device or program of origin
GBTMCVER= '3.3.0'              / telescope control software release
FITSVER = '1.1'                / FITS definition version for this device
DATEBLD=  'Thu Jun  7 20:15:13 GMT 2001' / time program was linked
SIMULATE=                    0 / Is the instrument in simulate mode?
DATE-OBS= '2000-10-25T13:57:17' / Manager parameter startTime
TIMESYS = 'UTC'                / time scale specification for DATE-OBS
TELESCOP= 'NRAO_GBT'           / Green Bank Telescope (Robert C. Byrd 100m)
OBJECT  = '0013+1527'          / Manager parameter source
PROJID  = 'RMP_DCR'            / Manager parameter projectId
OBSID   = 'test'               / Manager parameter scanId
SCAN    =                    3 / Manager parameter scanNumber
