sd.scantable.mx_quotient - Function

5.1.2 Form a quotient using ”off” beams when observing in ”MX” mode
Description

Form a quotient using ”off” beams when observing in ”MX” mode.

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 weight argument is used for time averaging off beams. You can set any options same as average_time.
