Reduction of Pointing and Focussing Scans

 

This is done by SOLVE POINTING  and SOLVE FOCUS  commands.

These commands will scan the current index for the specific data, and fit the data for each antenna. The results may be kept in a data file (Text format): use the option /OUTPUT filename NEW or /OUTPUT filename APPEND for this.

• for SOLVE POINTING, the measured pointing errors in the file may be used to replace the collimations in OBS (command CORRECTIONS, first two arguments), or the data file be used as a whole to solve for pointing coefficients with the program POINT (see the specific documentation on pointing).
• for SOLVE FOCUS, the measured error is to be added to the foc correction in OBS (command CORRECTIONS, third argument).

In both cases, option /PLOT will produce a graphic display of each fitted curve.
