NAME

uvimage - Create a 3D image from uvdata  

PERSON RESPONSIBLE

CATEGORIES

image conversion, analysis.  

DESCRIPTION

UVIMAGE makes a Miriad image datacube of the uvdata in a Channel - Baseline - Time order. Missing Baselines are replaced with 0s, Missing channels cause a fatal error. Flagged data are shown as 0, even if underlying values are non-0

This program expects the data to be homogeneous.

Related tasks:

        TVFLAG - good for inspection and flagging, but
                 only works in 8bit displays
        UVAVER - use this to cut down the number of times
        VARMAP - image maps of uv-variables
 

PARAMETERS

vis
The input uv-dataset name. No default.
select
This selects which visibilities to be used. Default uses all the data. See the Users Guide for information about how to specify uv data selection. e.g. 'select=ant(1)(5),-time(00:00,01:09)'
line
Linetype of the data in the format line,nchan,start,width,step "line" can be `channel', `wide' or `velocity'. Default is channel,0,1,1,1, which uses all the spectral channels.
view
Visibility 'amplitude', 'phase', 'real', or 'imaginary'. No calibration is applied by UVIMAGE. Default: amplitude
out
Output image. If no output image give, the visibility data will be scanned and a summary is given if there are integrations with missing (or extra) baselines and missing (or extra) channels. Currently the image cube is poorly labeled as CHANNEL, BASELINE, TIME with no real meaningful coordinates. See mode= below for other orderings of axes.
mode
This controls in what order the cube is written 1: CHANNEL-BASELINE-TIME (default) 2: TIME-CHANNEL-BASELINE 3: TIME-BASELINE-CHANNEL
ignore
Should flags be ignored? If true, the underlying data values are shown, even if non-zero. Default: false
