Hi Chris,
4 Jy! Then it could be the maser itself! But how did you get 1.4%? I
may miss something, or my approach was too simplistic. I just took the
ratio of the line width to the bandwidth and got < 0.1%.
Cheers,
Sergei

Sergei,
An OH maser is typically about 3 kHz (0.5 km/s). So your sensitivity
is
down by 1.4%, ie a 300 Jy maser is equivalent to a 4 Jy continuum
source -
if you correlate with 5000 spectral channels.
Cheers
Chris
