DM-23983: Cannot apply crosstalk in Gen 3 DECam processing

README.md

@@ -12,3 +12,6 @@ These masks are turned in to LSST style mask images with the single `BAD` bad bi
 Any non-zero pixel in the BPM was assigned the `BAD` flag.
 We construct `meas_algorithms.Defects` from the mask.
 We update metadata and write the file back out to the appropriate path determined from the sensor number and time stamp.

+## Crosstalk
+The crosstalk terms contained here are the results processed from `obs_decam/decam/DECam_xtalk_20130606.txt` (7 May 2020; using github master) using the `obs_decam` `makeCrosstalkDecam.py` script.  The directory structure and filenames match what is done with the defects above.  These yaml files can be used to construct `lsst.ip.isr.CrosstalkCalib` python objects using that class's `readText` method.  Both intra- and inter- chip crosstalk terms are listed in the objects.
