# 99/03/19 by Brad Wargelin:
#
# "At the C and O edges, I used the BESSY measurements of the uv/ion shield
# transmission to estimate the above-edge net QE.  I tend to trust the
# SAO-measured QEs more than those from XRCF because the anode voltage was
# only twice the line energy instead of 4x, thus less continuum.  An
# exception is Fe-L, which has lots of lines (O-K thru 794 eV)--I weigh
# the XRCF results more heavily because of the heavier filtering."

# 99/04/23 dd modifications:
#
# added a guess point at 0.07 keV so that Penning 131A (0.095)
# value can be interpolated, keeping MCP QE about constant.
#
# carbon edge was given by:
#0.284	0	0	0.230
#0.285	0	0	0.150
# improve the agreement w/synchrotron by moving the 0.285
# point to 0.294 and adjust the drop at 0.285, and 0.294 to
# make a flat MCP QE curve...
# add points at 0.3, 0.31 and 0.32 also
#
# oxygen edge was given by:
#0.543	0.126	0	0.126
#0.544	0	0	0.118
# the edge is over a larger range in energy, however.
# move the two points 0.543 and 0.544 to 
# 0.530 and 0.550 and add an intermediate point at 
#
# Al edge included by:
# duplicating the 1.490 point at 1.550
# adding a point at 1.580 to define Al-K edge...
