[PIPE1D-23] Updating stellar templates in the calibration files

Relates — Fri, 25 Sep 2020 13:22:11 +0000

I'm running "tickets/~~PIPE1D-17~~" branch of drp_1dpipe (0.14.0_rc2) with an input stellar spectrum and with calibration files from "datapack_0.14.0_rc2". In the calibration files, stellar templates are stored in stars_templates_vlba37_2018 and specified in "calibration/calibration_config.txt". These templates have low spectral resolution (R<1000?) and with a wavelength sampling (~5 angstroms). For line-of-site velocity measurements in the GA science, we would need a higher resolution (R~5000) with a denser wavelength sampling.

It would be great if you could include stellar templates with a higher spectral resolution and with a wavelength sampling of 0.5-1 angstroms. The Xshooter library seems to be suitable in terms of the wavelength coverage and the spectral resolution. Alternatively, is it possible to use a set of custom templates in the current pipeline? I have tried to run the code with a custom template contained in a directory specified in calibration/calibration_config.txt. I got messages attached below. I'm sorry if I missed something but your suggestions are very helpful.
