+Updated Data
+============
+
+For DM-40164, Aaron Roodman went through the single raft data, and fixed several problems in the data used for the sensor transmission curves:
+
+For 4 Rafts the SLAC single raft data had only 6 wavelengths, not the 30 or 36 wavelengths from all other CCDs.
+For these rafts he used BNL good run data,
+There was 1 amp with NAN values, since the channel was non-functional during single raft testing.
+For this channel he took values from the mean the other amplifiers.
+For 3 amps the signal raft values clearly have problems, with values at 0 or under 30% in g,r,i bands.
+2/3 were channels with problems during the single raft testing.
+These 3 channels are all currently functional.
+For these he took values from the average of the other good amp values.
+Both BNL and SLAC single raft data have anomalously high QE values at 1075 and 1100 nm, compared to the expected level from Si absorption.
+He used the known Si absorption curves, coded up by Steve Ritz.
+So for all channels he adjusted the QE just at 1075 and 1100 nm from the theoretical QE curve, normalized to the measured values at 750nm.
+
+The parquet file in this directory was copied from https://github.com/aaronroodman/lsstcam-notebooks/blob/main/Raft/qe_raft_allvalues_nircorrected_20230725.parquet as part of this ticket.

+The following table shows the source of data for each of the rafts:
