In the following example, PIMMS is used to predict the count rate in the XSPECT LEPC detector for a source with a thermal Bremsstrahlung spectrum with kT = 1 keV and NH = 1.0e21, and a rate in the ASCA SIS of 1 cps.

Reading mission directory, please wait
* PIMMS simulation product is COUNT
count rates for various instruments or intrinsic fluxes can be estimated
<--- Use 'PRODUCT' to simulate images
* Current model is BREMSSTRAHLUNG, kT= 10.0000 keV; NH = 1.000E+21
<--- Use 'MODEL' command to change
* By default, input rate is taken to be
Flux ( 2.000- 10.000 keV) in ergs/cm/cm/s
<--- Use 'FROM' command to change the default
* Simulation product will be
Count rate in ASCA SIS
<--- Use 'INSTRUMENT' command to switch to another instrument

* For thermal Bremsstrahlung model with kT= 1.0000 keV; NH = 1.000E+21
and 1.000E+00 cps in ASCA SIS
(Model normalization = 2.894E-02)
* PIMMS predicts 9.841E+00 cps with SXG LEPC
