Parameters of the source:
a) identification
b) coordinates ( 
, 
), accurate to 1''
c) epoch and reference for these coordinates
d) heliocentric radial velocity in km s 
. The
convention 
is followed
e) number of wavelength ranges (between 1 and 64)
Parameters for each of the up to 64 wavelength regions:
f) begin wavelength, corrected for (d) (in 
m)
g) a central reference wavelength, corrected for (d)
(in m) (avoid lines)
h) end wavelength, corrected for (d) (in m)
i) expected flux density (Jy) at the reference wavelength
(in m)
j) expected peak flux density (Jy) within the chosen
wavelength range (in m)
k) required signal-to-noise ratio SNR at reference wavelength.
