The INSTTAUR packet lists the header items which define the state of TAURUS 2. The header records should be as follows:
TAUCAMER= CHAR / Name of camera (f/2 or f/4) TAUFRAT = REAL / F ratio of camera (2.11 or 3.96) TAUSCALE= REAL / Plate scale (23.25 or 12.40 arcsec/mm) TAUMASK = CHAR / Name of aperture mask TAUFFILT= CHAR / Name of focal plane filter TAUIRIS = INTEGER / Iris diameter (mm) TAUPFILT= CHAR / Name of pupil plane filter TAUETALO= CHAR / Name of etalon in beam TAUFOCUS= REAL / Camera focus (microns) TAUDOORS= CHAR / Status of access hatches TAUTEMP1= INTEGER / Temperature at focal plane (0.1K) TAUTEMP2= INTEGER / Temperature at etalon (0.1K) TAUTEMP3= INTEGER / External temperature (0.1K) TAUPRES1= INTEGER / Pressure in etalon cavity (mbar) TAUPRES2= INTEGER / External pressure (mbar) TAUIVL = CHAR / Status of N2 inlet valve TAUOVL = CHAR / Status of N2 outlet valve CSCEXT = LOGICAL / CS100 external control enabled ? CSCINT = LOGICAL / CS100 integration enabled ? CSCGAIN = INTEGER / CS100 servo gain CSCTICO = INTEGER / CS100 servo time constant CSCLOOP = CHAR / Status of CS100 servo loop CSCVOLTS= INTEGER / Name of etalon being servoed CSCXOFF = INTEGER / CS100 X-offset CSCYOFF = INTEGER / CS100 Y-offset CSCZOFF = INTEGER / CS100 Z-offset CSCZSTAR= INTEGER / Start position for etalon scan CSCZSTEP= INTEGER / Step size for etalon scan CSCNSTEP= INTEGER / No of steps in etalon scan CSCRAMP = CHAR / Single or double-side ramp ? TAUFPSTE= INTEGER / Number of IPCS frames per etalon step PAOFFSET= REAL / Instrument p.a. - telescope p.a. (degs)
