unless otherwise noted.
The Ir optical constants are in 065o_optconsts_merged.rdb
The multi-layer surface parameters are in 065o_layers_merged_no_ol.rdb
The following plots shows the reflectivity from the surface multi-layer for the nominal grazing angles for the four HRMA shells. These are single reflections. The bumps in the high energy tail are due to the surface layers. The tabulated reflectivities are also available:

065o_optconsts_merged.rdb is the official set of Ir optical constants.
See Ping's email on how he created optconsts_065o.rdb
A multilayer_reflect compatible specification file
is available:
065o_layers_merged_no_ol.rdb.
The surface parameters are averages of those for the different energy
ranges, which are available here.

Subject: New Optical Constant Table
Date: Fri, 17 Nov 2000 13:46:45 -0500
From: Ping Zhao <zhao@head-cfa.harvard.edu>
Hello everyone,
Following I mentioned in our meeting this week, I just did a refit of the optical constant joints, which made some minor changes at the joint bewteen Gullikson and synchrotron at around 0.96keV and two synchrotron-synchrotron joints at around 2.02keV and 2.90keV. This refit smoothed out some very small jitters at those joints appeared in the previous version (991220).
The new OC table is at the same location: /data/ping3/HRMA_refl/optconsts_065/optconsts_065o.rdb
The previous version is at
/data/ping3/HRMA_refl/optconsts_065/991220/optconsts_065o.rdb
in case you want to see the difference.
This OC table is based on the synchrotron sample 065 data with overlayer fitting. The number of energies is the same as the previous version - 1040 energies. But there are some small shifts of energy levels at those joints.
Diab, please use this table for the new raytrace.
Cheers,
Ping
