scopeinpython.utils

Small numerical/radiometric helpers used by RTMo: sint (Simpson-like integration), photon-energy conversions, Planck’s law.

Small numerical utilities shared across the RTMo pipeline.

Direct ports of SCOPEinR/R/Sint.R, e2phot.R, ephoton.R and Planck.R.

scopeinpython.utils.sint(y, x)[source]

Trapezoidal integration of y over x.

Direct port of SCOPEinR::Sint.

Parameters:
Return type:

float

scopeinpython.utils.get_ephoton(lambda_m, const=None)[source]

Direct port of SCOPEinR::get.ephoton.

Parameters:

  • lambda_m (ndarray)

  • const (dict | None)

Return type:

ndarray

scopeinpython.utils.get_e2phot(lambda_m, E, const=None)[source]

Number of moles of photons corresponding to E Joules of energy at wavelength(s) lambda (m).

Direct port of SCOPEinR::get.e2phot.

Parameters:
