      Resolution Due: 24 March 2016 01:49 PM (8d 0h 0m)



I am trying to solve the mystery of a data set where GETJY is unable to find a sensible solution for one of the two IFs, while for the other it gives a null value for the uncertainty. It has made me realize that I do not understand how to interpret the content of the messages that GETJY reports.

In the below example, the third line says it used  "1 of 1 gain samples".  What might make it think there is only one sample? 

Line 8 indicates it used "35 of 36 total", but 35 of 36 what exactly? And then what do the 4 columns "bad, used, tot, bad" in line 8 actually refer to?

Thanks,
Lynn Matthews
