DBSP_DRP is a Data Reduction Pipeline for Palomar’s workhorse spectrograph DBSP. It is built on top of PypeIt. DBSP_DRP automates the reduction, fluxing, telluric correction, and combining of the red and blue sides of one night’s data. It adds several GUIs to allow for easier control of your reduction: select which data to reduce, and verify the correctness of your FITS headers in an editable table GUI manually place traces for a sort of manually “forced” spectroscopy with the -m option after manually placing traces, manually select sky regions and tweak the FWHM of your manual traces DBSP_DRP also provides a quicklook script for making real-time decisions during an observing run, and can open a GUI displaying a minimally reduced exposure in under 15 seconds. What's new: dbsp_splice script to allow users to manually splice two coadded files together. archived sensitivity functions for setups blue_300_3990_d55, blue_600_4000_d68 red_600_10000_d55 red_1200_7100_d68 red_1200_9400_d55 dbsp_trim script to trim a spliced spectrum to a final wavelength range of interest uses PypeIt version 1.6.0 improved documentation added Community Guidelines many bug fixes and improved stability Full Changelog: https://github.com/finagle29/DBSP_DRP/compare/v0.9.0...v1.0.0
