Also see Sault & Noordam (1995)
(A&AS 109, 593) for information and an example.
offset
'' is given, or if the ``sun
''
option is used, uvlin
normally fits for continuum just at the
offset or solar position. By using the ``twofit
'' option, uvlin
will fit for continuum at both the phase centre and the offset/solar
position.
Typical inputs to uvlin are:
UVLIN | |
in=line.uv | Input dataset before continuum subtraction. |
select | Leave unset to select all data. |
line | Leave unset to select all channels. |
chans=1,100,300,512 | Channels 1 to 100, and 300 to 512 inclusive |
contain only continuum emission. | |
out=line.sub | The output continuum subtracted dataset. |
order=1 | Use first order fit (which is the default). |
offset | The offset to apply. Probably leave unset. |
mode | Leave unset to get line data after |
continuum subtraction. | |
options | Probably leave it unset |
