[INSTRM-1456] Add a table for the guide offset

Thu, 18 Nov 2021 04:04:39 +0000

Please add a table to store the final guide offset from the nominal position calculated after each AGC exposure is done. The current proposal is

    agc_exposure_id = Column(Integer, ForeignKey('agc_exposure.agc_exposure_id'),
                             primary_key=True, autoincrement=False,
                             comment='AGC exposure number identifier')
    guide_ra = Column(FLOAT,
                      comment='The calculated FoV R.A. center [deg.]')
    guide_dec = Column(FLOAT,
                       comment='The calculated FoV Dec. center [deg.]')
    guide_pa = Column(FLOAT,
                      comment='The calculated FoV PA [deg.]')
    guide_delta_ra = Column(FLOAT,
                            comment='The calculated FoV R.A. offset [arcsec.]')
    guide_delta_dec = Column(FLOAT,
                             comment='The calculated FoV Dec. offset [arcsec.]')
    guide_delta_insrot = Column(FLOAT,
                                comment='The calculated InsRot offset [arcsec.]')
    guide_delta_az = Columnn(FLOAT,
                             comment='The calculated Az offset [deg.] (optional)')
    guide_delta_el = Columnn(FLOAT,
                             comment='The calculated El offset [deg.] (optional)')
    guide_delta_z = Column(REAL,
                           comment='The calculated focus offset [mm]')
    guide_delta_z1 = Column(REAL,
                            comment='The calculated focus offset for AGC1 [mm]')
    guide_delta_z2 = Column(REAL,
                            comment='The calculated focus offset for AGC2 [mm]')
    guide_delta_z3 = Column(REAL,
                            comment='The calculated focus offset for AGC3 [mm]')
    guide_delta_z4 = Column(REAL,
                            comment='The calculated focus offset for AGC4 [mm]')
    guide_delta_z5 = Column(REAL,
                            comment='The calculated focus offset for AGC5 [mm]')
    guide_delta_z6 = Column(REAL,
                            comment='The calculated focus offset for AGC6 [mm]')

We need the focus offset for all AGCs (delta_zx) and also the typical (mean?) value (delta_z).
