- Example: The SIAM should be changed such that the RGS angle of
incidence onto the gratings
is increased by 10arcsec. Due
to the focusing of the XRT, thus amounts to an off-axis angle of
The dispersion of the RGS is along the Z-axis, and the gratings are
arranged such that an increase of
is achieved by a rotation
of the spacecraft around the Y-axis in positive sense. Hence the
task is called with

- occasionally the minimization fails at the SLATEC level (SLATEC
error from DNLS1E). This cannot be circumvented, but slightly
different values of one of the input parameters remedy this.
