RSPModelNoPHA

class sherpa.astro.instrument.RSPModelNoPHA(arf, rmf, model)[source] [edit on github]

Bases: sherpa.astro.instrument.RSPModel

RMF + ARF convolution model without associated PHA data set.

Notes

Since there is no PHA data set, there is no correction for any AREASCAL setting associated with the data.

Methods Documentation

apply(outer, *otherargs, **otherkwargs) [edit on github]
calc(p, x, xhi=None, *args, **kwargs)[source] [edit on github]

Evaluate the model on a grid.

Parameters:
  • p (sequence of numbers) – The parameter values to use. The order matches the pars field.
  • *args – The model grid. The values can be scalar or arrays, and the number depends on the dimensionality of the model and whether it is being evaluated over an integrated grid or at a point (or points).
filter() [edit on github]
get_center() [edit on github]
guess(dep, *args, **kwargs) [edit on github]

Set an initial guess for the parameter values.

Attempt to set the parameter values, and ranges, for the model to match the data values. This is intended as a rough guess, so it is expected that the model is only evaluated a small number of times, if at all.

reset() [edit on github]
set_center(*args, **kwargs) [edit on github]
startup(cache) [edit on github]

Called before a model may be evaluated multiple times.
