autoflag.setnewtimemed - Function

2.1.1 Sets up the new time-median flagging method
Description

The newtimemed method uses a median-in-time filter. It follows the procedure of timemed but considering a median value from all time slots in a chunk.

The median is computed on a per-channel, per-baseline basis. The thr parameter multiplying the standard deviation of the data in a chunk sets the threshold for flagging. If the thr parameter is specified (e.g. thr = 3), all points with greater than three standard deviations away from the median are flagged.

Arguments


Inputs

	allowed:	string
	Default:	MODEL CORR DATA
expr	Expression to use
	allowed:	string

	Default:	false

Returns
bool
