GrismNRPGrismNRP
-
The rate of change of refractive index with wavelength
- Description:
- This attribute holds the rate of change of the refractive index of the
grism material with respect to wavelength at the reference wavelength
(given by attribute GrismWaveRGrismWaveR). The default value is 0.0 (the
appropriate value for a pure grating disperser with no prism). The
units of this attribute should be consistent with those of attributes
GrismWaveR and GrismGGrismG.
- Type:
- Double precision.
