Basic Information on sinbad
Task: sinbad
Purpose: Calculate Tsys*(on-off)/off* for autocorrelation data.
Categories: uv analysis
SINBAD is a MIRIAD task to calculate (ON-OFF)/OFF*TSYS for
autocorrelation data. The preceeding OFF and TSYS record
for each antenna is used. Flags on the OFF scans are ignored.
Flags on the ON scans are copied to the output file.
Missing TSYS can be replaced via the tsys= keyword as a last
resort, or the spectral window based systemp() UV variable.
Key: vis
The name of the input autocorrelation data set.
Only one name must be given.
Key: select
The normal uv selection commands. See the Users manual for details.
The default is to process all data.
Key: line
The normal uv linetype in the form:
line,nchan,start,width,step
The default is all channels.
The output consists of spectral channels only.
Key: out
The name of the output uv data set. No default.
Key: tsys
Value for flat tsys spectrum if neither band average systemp
nor full spectrum is available.
Key: options
Different computational output options (mainly for debugging).
Exclusively one of the following (minimum match):
'spectrum' Compute Tsys*(on-off/off). This is the default
'difference' Compute (on-off)
'ratio' Compute on/off
