ENR CTIO Blanco 4-m 2022-09-13

Date: 
Tuesday, September 13, 2022
Telescope: 
CTIO Blanco 4-m
Submitter: 
Gautham Narayan (2nd half), Tony Chen (1st half)
Submitter Email: 
gsn@illinois.edu
Observer Support: 
Wilson Liu
Night Assistant: 
Hernan Tirado
Also Present: 
Alberto Alvarez and Alfredo Zenteno
Problems: 

Updating propid for second half of night caused SISPI to throw an error. Fixed only by reseting propid to program for first half of night. Not a major issue since both halves are for the same program and the propid in the json files is used for the archive, but may mess up some summary statistics.

Comments: 

expnum 1134212 is bad, very elogated sources, the telescope might be nodding or moving while taking the exposure.

expnum 1134314 is not good but useful, slightly elongated sources.
