Add some of the PypeIt CALSPEC flux standards #195
Conversation

For the standards that already were in the pipeline, can you summarize what you did with the plots? e.g. |
|
Regarding the plots that got replaced, this happened simply as a result of running the spec_stats.py script that was already in the standards folder, so whatever change between the old plots and the new ones is from there. The script just sets log scaling on the y axis, and the x axis limits to min wavelength - 100 and min(12000 angstroms, wlmax) + 100. I can change this so its more consistent with the old plots going from ~3200 A to 1.1 micron (and update the .txt files too) I have checked bd02d3375 specifically and it seems that the old plot for that object is likely based on a version of the spectrum that did not have the extended wavelength coverage (or it was probably trimmed to only have wavelengths within the KCWI wavelength range). |
…d ones change the markers to blue x, and fix the x limits to be 3200 A to 11000 A. y limits are simply set to the maximum and minimum flux values within the KCWI wavelength range.

Sounds good to me, thanks for the explanation. I think you're right, the last time we added to the standards we must have forgotten to run the stats. Sending to Rosalie for final approval, then we'll merge it in. |
updated the information in the kcwi_stds_starlist.txt file. Added stars in the standards folder that were previously unlisted, and added information on the WD stars added. Removed a few existing standards that were the same as the WD stars.
Last updates taking into account the standards I added. Also adds entries for missing stars.
Added a few of the PypeIt CALSPEC flux standards to the stds folder. These are all WD stars with V_mag > 12, and wavelength coverage sufficient for very red KCRM setups. All stars are observable from Keck II with a maximum elevation of > 45 degrees.
I have not updated the spec_stats or stds_stats text files as I was unsure how to interpret some of the column names.
