chandra_aca.dark_model.get_sbp_pars

chandra_aca.dark_model.get_sbp_pars(dates)

Return smooth broken powerlaw parameters set(s) at dates.

This is based on the sbp fits for the darkhist_zodi_m14 histograms in /proj/sot/ska/analysis/dark_current_model/dark_model.ipynb.

The actual bi-linear fits (as a function of year) to the g1, g2, g3, x_b, and ampl parameters are derived from fits and by-hand inspection of fit trending.

This is only accurate for dates > 2007.0.

Parameters:

dates

one or a list of date(s) in DateTime compatible format

Returns:

one or a list of parameter lists [g1, g2, g3, x_b, ampl]
