About the Chandra Radiation Environment Summary

Current orbit start, configuration, and current fluxes/orbital (CRM and Goes) fluences come from:
/data/mta4/Space_Weather/CRM/Data/CRMsummary.dat
EPHIN rates come from: /pool14/chandra/chandra_psi.snapshot
Current unattenuated ACE comes from: /data/mta4/Space_Weather/ACE/Data/fluace.dat
Current ACE attenuated data comes from: /export/acis-flight/FLU-MON/current.dat
Upcoming spacecraft configuration and radzones come from: /proj/sot/ska/data/arc/iFOT_events files

We calculate the attenuation factors to be used for GOES calculations from the CRM data:

att_factor=	crm_flx_att/crm_flx
att_flu_factor=	crm_flu_att/crm_flu
future_attenuated_fluence=	current_attenuated_fluence + (curr_unattenuated_flux * future_attenuation_factor)
where:
future_attenuation_factor=	hrc_time0 + acis_bare_time1 + acis_hetg_time0.2 + acis_letg_time0.5
