The thermal spectra used in SPEX now automatically include atomic line
emission for any spectrum that extends below 8 keV.  Previously, I had
believed that this was enabled shortly after the launch of HESSI, but
discovered after the Berkeley workshop that it was not functional.
Thanks to Arnold Benz for calling this to my attention during this
workshop even though I stated that I thought it was working at the time.
The revised routines have been placed in $SSW/packages/xray/idl and will
propagate at your next update.
