sd.scantable.auto_quotient - Function

5.1.2 Automatic quotient for coordinated scans
Description

This function allows to build quotients automatically. It assumes the observation to have the same number of ”ons” and ”offs”.

The formula to get result depends on the preserve paramter. If it is True, the continuum will be preserved while if it is False, the continuum will be removed. The equation used are

T *= TOF F-ON--- T OFF,
 a    sys OF F     sys

if preserve is True, while

 *    OFF ON      ON
Ta = Tsys  OF-F-- Tsys ,

if preserve is False.

The mode argument controls the on/off decition mode. If mode is ’paired’ (default), it identifies ’off’ scans by the trailing ’_R’ (Mopra/Parkes) or ’_e’/’_w’ (Tid) and matches on/off pairs from the observing pattern. On the other hand, ’time’ finds the closest off in time.

Note that the verify argument is not yet implemented.
