1. FOC Exposure Simulator - FOCSIM
The FOC Exposure Simulator, FOCSIM, provides the capability to simulate almost any FOC exposure and to calculate diagnostics about the image. FOCSIM, the FOC exposure SIMulator, uses the most current description of the FOC and its filters along with an input spectra (either from an on-line catalog or user-supplied file) to simulate an image from the FOC and provide the count rate within the image. ... Where to Find FOCSIM . ... How to run FOCSIM . ... What Sources can FOCSIM Simulate . ...

Next: *upspecrdf, downspecrdf* - Transform Up: Spectral Analysis Previous: *grid_plot* - Plot Results . The conversion of count rate to flux depends on the intrinsic spectrum of the source, so xflux must be used in conjunction with fit . Fit generates a table of the best fit intrinsic spectrum ( _int.tab extension). xflux uses this table to calculate either the integrated flux between two energy limits or the flux density at a specific energy. ... This produces ``..._obs.tab'' file. ...
