get_ap_eff

function get_ap_eff(freq[, elev])

Function to return a default aperture efficiency, given an observing frequency. Used in the calibration routines. The formula for Q-band comes from the PTCS Project Note 43 by Balser, Prestage & Nikolic. At other frequencies, the value returned is just an educated guess, at this point.

Examples 
    apeff = get_ap_eff(18.5,45.0)
    print,apeff
