Problem when reduce the keck_lris_blue data #291

Closed fgscc closed 8 months ago

fgscc commented 1 year ago

I am trying to reduce the keck_lris_blue data [target coodinate RA, DEC (15:39:32.14, +50:27:38.9)], there are hundreds of the science files, and I am trying to reduce these five files: LB.20180617.27634.fits LB.20180617.28189.fits LB.20180617.28291.fits LB.20180617.28380.fits LB.20180617.28459.fits

The reduction of the file LB.20180617.27634.fits is well done and I can obtian the spectrum. But for the rest four files, when the software tries to reduce, the software stoppes, and reports "No trace locations".

I check the 2D file for these files, and find for LB.20180617.27634.fits, the spectrum seems more obvious than the other four files. Does it means the software can not find the spectrum location to trace?

If so, how can I solve the problem?

Here are some attachments including: the problem report, the orignal 2D spectrum for 5 files.

please join the PypeIt Users Slack and discuss there.

It's easier for these types of issues than GitHub
