98/02/03 DEFECT IN PROGRAM sort_rms
SYMPTOM: Antenna type was NULL for stations COCO and KERG in GPS Weeks
936 through 939. Antenna offsets set to 0.0000.
PROBLEM: Antenna records in site_info file switched by accident.
CORRECTION: Warning printed by sort_rms if NULL antenna type detected.
CODED BY: Dulaney 98/01/16
VERSION: 9801.16
SOURCE: /proc/gl/Source_gps/Sort_rms (Buster and Vulcan)
EXECUTABLE: /proc/gl/Bin_gps (Buster and Vulcan)
NOTES: Input to sort_rms is page4.log file. STATION CENSUS section
keyed on for antenna test. Pseudo-code for NULL test and
sample output attached, per Schenewerk.
while line can be read from page4.log,
if characters 2 thru 14 equal "STATION NAME:"
then read third field of line into array "sta_name".
if characters 2 thru 10 equal "ANTENNA ("
then read string between parentheses into array "ant_type".
for i from 0 to number of baselines,
if ant_type[i] equals "NULL"
then print DANGER message for station sta_name[i].
