-The file `rawData/raw/c4d_150227_012718_ori-stripped.fits.fz` is taken from [ap_verify_hits2015](https://github.com/lsst/ap_verify_hits2015), with all of the image data set to 0 to reduce file size.
+* `rawData/raw/c4d_150227_012718_ori-stripped.fits.fz` is taken from [ap_verify_hits2015](https://github.com/lsst/ap_verify_hits2015), with all of the image data set to 0 to reduce file size.
 This file contains all HDUs in the original file, and is useful for testing handling of "normal" multi-HDU DECam data.
-The `rawData/raw/c4d_150227_012718_ori-stripped-shuffled.fits.fz` is identical to the above except that the HDU ordering has been randomly shuffled.

+* `rawData/raw/c4d_150227_012718_ori-stripped-shuffled.fits.fz` is identical to the above except that the HDU ordering has been randomly shuffled.
 This file is useful for testing reading of files that may not have the "typical" HDU ordering.
 
-The file `rawData/raw/raw.fits` contains the imaging data from two detectors (1 and 25).
+* `rawData/raw/raw.fits` contains the imaging data from two detectors (1 and 25).
 
-The `hits2015-zeroed` directory contains files from the `ap_verify_ci_hits2015` dataset that have had their image data set to the HDU number and then Hcompressed with `fpack` to reduce their size.
+* `hits2015-zeroed/` contains files from the `ap_verify_ci_hits2015` dataset that have had their image data set to the HDU number and then Hcompressed with `fpack` to reduce their size.
 These files are not useful for testing pipelines, but they can be used to test butlers (ingestion and gen2 to gen3 conversion).
-`calibingested/` is a gen2 calib repo linking to the hits2015 calibration files.
-`ingested/` is a gen2 butler repo linking to the hits2015 raw files.

+* `ingested/` is a gen2 butler repo linking to the hits2015 raw files.
+
+* `pipeline-calibs/` contains a LSST Science Pipelines built master bias frame and corresponding master flat frame.
+These were constructed using `cp_pipe`'s `constructBias.py` and `constructFlat.py`.
+Both files are for CCD 47, but have had all of the image data set to 0 to reduce file size.
+They are used to test parsing of calibration products as part of the gen2 calibration ingestion process.
