A note on these floats from Mark Prater:
  Since the traditional RAFOS T/P tends to be just a point measurement, 
what I will do is take the first T and P after the navigation fix and 
stick it in the RFC file.  Since I don't do traditional measurements 
when I profile, I'll have to add a null in place of the T or P at those 
times.  I'll just leave the "w" [vertical velocity] field as zeros.
