irispy.iris_tools.calculate_photons_per_sec_to_radiance_factor(wavelength, detector_type, spectral_dispersion_per_pixel, solid_angle)[source] [edit on github]

Calculates multiplicative factor that converts counts/s to radiance for given wavelengths.

Parameters:
  • wavelength (astropy.units.Quantity) – Wavelengths for which counts/s-to-radiance factor is to be calculated
  • detector_type (str) – Detector type: ‘FUV’ or ‘NUV’.
  • spectral_dispersion_per_pixel (scalar astropy.units.Quantity) – spectral dispersion (wavelength width) of a pixel.
  • solid_angle (scalar astropy.units.Quantity) – Solid angle corresponding to a pixel.
Returns:

radiance_factor – Mutliplicative conversion factor from counts/s to radiance units for input wavelengths.

Return type:

astropy.units.Quantity
