NuRadioReco.utilities.ice module
(old) implementation of ice models
Only returns one of two values depending on whether the depth is below or above 0 (assumed to be the ice-air) interface.
Warning
This function is used internally in some modules, but should not
be used in new user code. Please use the NuRadioMC.utilities.medium
module instead
- NuRadioReco.utilities.ice.get_refractive_index(depth, site='southpole')[source]
Get refractive index for depth
For sites that are not at the poles, always returns the refractive index of air (1.000293). Otherwise, returns 1.3
Warning
This function is only used internally. New user code should use the ice models in
NuRadioMC.utilities.mediuminstead- Parameters:
- depthfloat
The depth
- sitestr, optional
The site to use. For sites on land (not in-ice), the refractive index returned is always that for air.
- Returns:
- nfloat
The refractive index. For land-based sites, this is always n_air=1.000293; for in-ice sites, returns n_ice=1.3 or n_air depending on the depth.
