GETANT is getting the antenna information and is objecting to antenna
numbers in excess of the limits compiled into the code (90).  It is
used to compute average parallactic and zenith angles and the like.
No data are deleted just for having antenna numbers out of range.  Of
course, you chould not attempt to calibrate such data - but with
models calibration is not relevant.
