eso_sky_calc#

class arte.photometry.eso_sky_calc.EsoSkyCalc(**kwargs)#

Bases: object

Calling sequence:

sky = EsoSkyCalc(**kwargs)

the full list of keywords parameters and defaults is in the help page

Examples

Plot sky radiance for airmass=2 and full moon

>>> sky = EsoSkyCalc(airmass=2, moon_sun_sep=180)
>>> plt.semilogy(sky.lam, sky.flux)

Retrieve dictionary of default values

>>> defdict= EsoSkyCalc.default_values()
>>> defdict['observatory'] == '3060m'
