While creating my new Crater graph I ran across this bit of documentation that shows the silicon to water correction factor has indeed been added. FYI.
# CRaTER (GCR+SEP) dose rates for individual and combined detectors
# from 2009-06-26 DOY:177
# through 2017-03-26 DOY:085
#
# Columns are separated by a tab character.
# All dose rate units: cGy / day
# All dose rates have a silicon to water correction applied and are altitude corrected to the lunar surface.
#
