[daip] UVPLT doesn't plot all subarrays as advertised

[Leonia Kogan]

Michael,

Yes you are right UVPLT has had a problem with multi FREQID/SUBARRAY data,
if you want to plot all af them specifiing SUBBARAY=0 or/and FREQID=0.

If you selected SUBBARAY=0 or/and FREQID=0, then UVPLT chooses all
FREQID/SUBARRAY available at the data. At this choosing UVPLT can come
across to the combination of FREQID/SUBARRAY which does not present at
the data. UVPLOT has died at tyhis point. I fixed the problem. The new
version will be available after MNJ.


I have checked the new version with my data that had two combinations:
1. FREQID=1, SUBARRAY=1
2. FREQID=2, SUBARRAY=2

The old version died if FREQID=0, SUBARRAY =0,1,2 or
                        SUBBARAY=0, FREQID =0,1,2

I suppose UVPLT has died with your data also if SUBARRAY=0. If UVPLT
plots the last SUBBARAY instead then there is another problem which I
do not comprehend yet. Please elucidate for me the situation.

That is wrong. SUBARR is stored at the beginning of SCAL:

      JSUB = SUBARR

And then restored at the end:

 220  IRET = 0
      SUBARR = JSUB
      GO TO 999

UVPLT doesn't plot all the subarrays with SUBAR = 0.

The problem seems to be that subroutine SCAL resets the variable
SUBARR to be the last subarray as it loops through the subarrays, and
then the rest of the program only plots the last one.
