== Fits header cards/keywords and Q* metadata issues ==


If you need to manually change the FITS header keywords on existing data (i.e., if the metadata was missing), follow this example to edit the raw data and then inform Sergey and Greg to re-copy that night's data. Note that the new commands discussed below (i.e. qdata_fix) would be run from a machine like zeus or janus through your personal account. 

Run this from zeus or janus. 

1. if need to fix one observation
{{{qdata_fix <instrument> <utdate> <obsnum> <index>}}}

Program will ask for confirmation of program for the target.

For exmaple
{{{
 > qdata_fix.sh lrs2 20230420 17 1279

Found that program for the #1279 is PSU23-2-013
Is this correct? [<Enter> to conitue with current value, type a correct one or q to exit]

}}}

2. if multiple observations need to be fixed
{{{for obsn in 4 5 6 7 8 9 10 11 ...; do qdata_fix <instrument> <utdate> <obsnum> <index>; done}}}
