• qpspec - Create spectral data set from a qpoe file.
• counts_plot - Plot the observed and/or predicted counts distributions.
• bal_plot - Plot the current BAL histogram (Einstein IPC data only).
• show_models - Display the current model parameters.
• fit - Find best-fit model values using a simplex minimization.
• singlefit - Compare fixed-parameter model with data.
• search_grid - Perform a chisquared grid search.
• grid_plot - Plot the chisquared grid with contour lines.
• pkgpars - spectral package parameter pset
• xflux - Compute X-ray flux from models
• hxflux - Calculates the flux and luminosity for a ROSAT HRI source.
• dofitplot - Do fit and then counts_plot
• intrinsicspecplot - Plot the emitted and observed spectrum

( Type help <topic> for info on any of the following: )
