- irispy.utils.calculate_photons_per_sec_to_radiance_factor(time_obs, response_version, wavelength, detector_type, spectral_dispersion_per_pixel, solid_angle)¶
Calculates multiplicative factor that converts counts/s to radiance for given wavelengths.
astropy.time.Timeobject, as a kwarg, valid for version > 2) – Observation times of the datapoints. Must be in the format of, e.g., time_obs=parse_time(‘2013-09-03’, format=’utime’), which yields 1094169600.0 seconds in value. The argument time_obs is ignored for versions 1 and 2.
int) – Version number of effective area file to be used. Cannot be set simultaneously with response_file or pre_launch kwarg. Default=4.
astropy.units.Quantity) – Wavelengths for which counts/s-to-radiance factor is to be calculated
str) – Detector type: ‘FUV’ or ‘NUV’.
astropy.units.Quantity) – spectral dispersion (wavelength width) of a pixel.
astropy.units.Quantity) – Solid angle corresponding to a pixel.
Mutliplicative conversion factor from counts/s to radiance units for input wavelengths.
