IndexError: index 2 is out of bounds for axis 0 with size 2

The noise information is missing in d, causing the spectrum to be unable to load. This happens for multiple sources, here are all the names that I found with this error: LRL 405, KPNO 1, KPNO 2, KPNO 12, KPNO 4, KPNO 5, KPNO 6, KPNO 7, MHO 4, KPNO 9, CFHT 3, ITG 2, CFHT 6, CFHT 4, 2MASS J04414825+2534304, 2MASS J04442713+2512164, 2MASS J04574903+3015195.

yes, unfortunately some of the spectra passed to us had no noise vectors. I'll see if I can do a bypass, but please be patient

hmmm, I am unable to replicate this error; make sure SPLAT is pointing to the write data directory
