pylayers.antprop.loss.lossref_compute(P, h0, h1, k=1.3333333333333333)

compute loss and reflection rays on curved earth

P : float |list

if len(P) == 1 => P is a distance if len(P) == 4 => P is a list of [lon0,lat0,lon1,lat1]

where : lat0 : float |string

lon0float |string

longitude first point (decimal |deg min sec Direction)

lon1float |string

longitude second point (decimal |deg min sec Direction)

h0float:

height of 1st point

h1float:

height of 2nd point

k : electromagnetic earth factor

dlossfloat

length of direct path (meter)

dreffloat

length of reflective path (meter)

psyfloat
