Net outgoing longwave radiation requires solar_rad but no function exists by the name solar+rad

[parallax-geo]

For the calculation of net outgoing longwave radiation pyeto.net_out_lw_rad(tmin, tmax, sol_rad, cs_rad, avp) it requires solar radiation sol_rad as argument. In the documentation it says to compute that use the sol+rad function. But no function by that name exists. Incoming shortwave radiation can be calculated using various functions but outgoing solar radiation there is none.
