DM-45391: Add baseline ComCam curated calibrations for optics, filters, and sensor qe.

comCam/transmission_filter/README.md

@@ -0,0 +1,20 @@
+This directory contains baseline filter transmission curves for the LSSTComCam instrument.
+We do not have specific filter scans for the LSSTComCam filters, so the data for the curves are from version 1.9 of the [LSSTCam baseline u, g, r, i, z, y filter files in the throughputs repo](https://github.com/lsst/throughputs/tree/1.9/baseline).
+
+Data Processing
+---------------
+
+To generate these files, one clones a local copy of the [throughputs
+repo](https://github.com/lsst/throughputs), checks out version 1.9,
+and sets up the repo with eups:
+```
+git clone https://github.com/lsst/throughputs.git
+cd throughputs
+git checkout 1.9
+setup -r . -j
+```
+In the obs_lsst package, one then runs the script to write the files
+using the througputs data:
+```
+python ${OBS_LSST_DIR}/python/lsst/obs/lsst/script/write_comcam_filter_files.py
+```
