hcipy.atmosphere.make_las_campanas_atmospheric_layers(input_grid, cn_squared=None, outer_scale=None, r0=0.16, L0=25, wavelength=5.5e-07)

Create a multi-layer atmosphere for the Las Campanas Observatory site.

The layer parameters are taken from [Males2019] who based it on site testing from [Prieto2010] and [Osip2011] .

Parameters:

input_gridGrid

The input grid for the atmospheric layers.

cn_squaredscalar

The integrated Cn^2 value for all layers. If this is None (default), then a Fried parameter of 0.16m at 500nm is used.

outer_scalescalar or None

The outer scale of the atmosphere. If this is None (default), then an outer scale of 25m is used.

r0scalar

The integrated Cn^2 value for the atmosphere. This parameter is deprecated and should not be used. Use cn_squared instead.

L0scalar

The outer scale of the atmosphere. This parameter is deprecated and should not be used. Use outer_scale instead.

wavelengthscalar

The wavelength in meters at which to calculate the Fried parameter (default: 550nm). This parameter is deprecated and should not be used. Use cn_squared instead.

Returns:

list

A list of turbulence layers.
