X
g = 1 + h_2 T_lapse
amb
gconst
with
h1 = 2, h2 = -6.5 (note this h2 is defined differently to that in the previous equation),
gconst
where Jatm is the effective brightness temperature of the sky.
The routine will return immediately if entered with bad status. Errors will be reported and bad status
returned if:-
-
TAUZ is less than 0
-
AIRMASS is less than 0
-
WAVELENGTH is less than or equal to 0
-
T_AMB is less than or equal to 0
-
ETA_TEL is outside the range 0 to 1
-
B is outside the range 0 to 1
