msplot.avedata - Function

1.3.3 Specify which data is to be averaged in the MS (or selected MS).


Description

No description here at the moment. This method is under active development and is changing frequently. Documentation will be provided when development settles down.

Arguments





Inputs

chanavemode

Indicate what if any averaging should be done on the selected channels.The channel selection and averaging is done via the spw parameter. Valid values are:

none: No averaging, default value step: Plot every nth point scalarstep: incoherent average of every n points vectorstep: coherent average of every n points scalarchunk: incoherent average of blocks with n points vectorchunk: coherent average of blocks with n points

allowed:

string

Default:

none

corravemode

Indicate what if any averaging should be done on the selected correlations. See chanavemode for a detailed description of the valid values. Valid values are: none, step, scalarstep, vectorstep, scalarchunk, or vectorchunk

allowed:

string

Default:

none

datacolumn

Indicate the visibility data to be averaged. Valid values are: DATA CORRECTEDDATA MODELDATA

allowed:

string

Default:

DATA

averagemode

Indicate the mode for channel and/or time averaging. Valid values are: vector scalar

allowed:

string

Default:

vector

averagechan

Indicate the number of channels to average. The default value of 1 means no channel averaging.

allowed:

string

Default:

1

averagetime

Indicate the length of time interval to average. Valid values are double values of time in seconds. The default value 0 means no time averaging.

allowed:

string

Default:

0

averageflagged

Indicate either flagged or unflagged data to average.

allowed:

bool

Default:

false

averagescan

Indicate whether time averaging cross scan boundaries.

allowed:

bool

Default:

false

averagebl

Indicate whether averaging cross baseline boundaries.

allowed:

bool

Default:

false

averagearray

Indicate whether averaging cross array boundaries.

allowed:

bool

Default:

false

averagechanid

Indicate whether using averaged channel id or not.

allowed:

bool

Default:

false

averagevel

Indicate whether calculating averaged velocity id or not.

allowed:

bool

Default:

false

Returns
bool

Example

 
# create a msplot tool and set the subset data for plotting.  
  mp.open( msname=’./data/3C273XC1.ms’);  
 
# TO COME  
  mp.average( ??? )
