New spectral analysis commands in EXSAS '97:
FIT/SPECTRUM, MODEL/SPECTRUM:
An inconsistent definition of the number of model parameters in
the spectral models *tblm* and *tbef* has been corrected. The bug
resulted in warnings like "Unaligned access......" but did not
affect the fitting results.
Also: the maximum number of grid steps has been changed from 50 to 100.
INTEGRATE/FLUX:
Checks now if the integrated flux was computed taking the galactic
absorption model GAMM() into account. If the integrated flux is the
absorbed flux a note is given on the screen. The source code has been
revised and optimized.
CONVERT/RATE_TO_FLUX:
New command: The program computes the energy flux for a given count
rate and spectral model. See the online help for a detailed description
of the command syntax. Additional background information on how the
command works in detail can be found on the EXSAS Spectral Analysis

CALCULATE/GALACTIC_NH:
The unit of the output has been changed from 10^20 1/cm^2 to
10^21 1/cm^21 to reach agreement with the units of Nh used in
the parameter files of the spectral fitting procedures.
In non table mode the *unit* of Nh was given as 10^20 1/cm^2
although Nh actually was computed in units of 10^21 1/cm^2. This
is corrected now.
