BB_TEMPERATURE

BB_TEMPERATURE

Name


    BB_TEMPERATURE

Purpose


    This function will return the blackbody temperature corresponding
    to either the provided spectral radiance or the spectrally-
    integrated radiance at the specified wavelength or within the
    specified bandpass.

Category


    Radiometry.

Calling Sequence


    Result = $
      BB_TEMPERATURE( radiance, $
                      wavelength, $
                      LIMITS=limits, $
                      UNITS=units

Inputs


    radiance
      A scalar indicating the spectral radiance or the
      intgrated spectral radaince for which the blackbody
      temperature is to be determined.
    wavelength
      A scalar variable containing the wavelength for
      which you would like to compute the blackbody
      temperature [microns].

Keyword Parameters


    LIMITS
      A two-element vector defining the lower and upper
      limit of the bandpass over which the provide spectral
      or spectrally-integrated radiance defined [microns].
    UNITS
      A scalar indicating the units of the provided radiance
      value, namely
          0: W / m^2 / sr / micron (DEFAULT)
          1: W / cm^2 / sr / micron
          2: mW / m^2 / sr / micron
          3: mW / cm^2 / sr / micron

Restrictions


    The blackbody temperature must be in the range 1 to 1000000K

Return Value


    Result will contain the blackbody temperature for the provided spectral
    or spectrally-integrated blackbody radiance

Side Effects


    None
