To reduce optical pointing data, work on BURE02, in the [OBS.POINTING] directory, and use POINT, specifying the RLTDATA:[OBSERVER.POINTING] Date.OPT file as input:
$ SET DEF [OBS.POINTING] $ POINT POINT> FILE Date OPTICAL POINT> READ Antenna_Number POINT> SOLVE POINT> [ Other commands ]The file is fetch by default from directory RLTDATA:[OBSERVER.POINTING]. A fit will be made with the free parameters IAZ IEL+COV COH MVE MVN, and all other parameters fixed at zero. A fit with more free parameters (e.g. ELEC and NPE) can be made using the commands :
POINT> PARAMETER NPE/FREE POINT> PARAMETER ELEC/FREEOptical pointing gives only the sum IEL+COV. The zero of the elevation encoder is an antenna constant. After a fit by POINT all parameters should be replaced in the antenna-station parameter file.
