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. ...

... In most cases it will however be necessary to compute an appropriate airmass using the COMPUTE/AIRMASS . ... It is important to keep in mind that ``mean airmass'' and ``mean atmospheric extinction correction'' are different from the values at mid-exposure, especially for larger zenith distances. ... For reasonable combinations of exposure time and zenith distance, the weighted mean airmass supplied by COMPUTE/AIRMASS should be appropriate. ...
