Workspace Method gas_scattering_coefXsecConst

Description

Calculates the spectrum of scattering coefficient matrices.

It calculates the spectrum of scattering coefficient matrices from 
constant spectrum of scattering cross section matrices, atmospheric pressure,
temperature for one point in the atmosphere. Basically, it multiplies
the cross sections with the number density of gas molecules under the
assumption of an ideal gas. The result is returned in gas_scattering_coef. The
atmospheric  pressure  and  temperature  state  has  to  be  specified
by  rtp_pressure, rtp_temperature.
