  <shortdescription>Fit/subtract a spectral baseline </shortdescription>

​

  <description>

Task sdbaseline fits and/or subtracts baseline from single-dish spectra.

Given baseline parameters (baseline type, order, etc.), sdbaseline 

computes the best-fit baseline for each spectrum by least-square fitting 

method and, if you want, subtracts it. The best-fit baseline parameters 

(including baseline type, coefficients of basis functions, etc.) and 

other values such as residual rms can be saved in various formats 

including ascii text (in human-readable format or CSV format) or baseline 

table (a CASA table).

Sdbaseline has another mode to 'apply' a baseline table to a MS data; 

for each spectrum in MS, the best-fit baseline is reproduced from the 

baseline parameters stored in the given baseline table and subtracted. 

Putting 'fit' and 'subtract' into separate processes can be useful for 

pipeline processing for huge dataset.
