1.ii: Data selection options

Logged on 07/09/2009 04:41:30 PM

The runtime options window contains further options for data selection.

For calibration purposes Measurement Sets typically have three columns, DATA, CORRECTED_DATA and MODEL_DATA. You can select which one of these you'd like to examine (the simulated Measurement Sets should only have something in DATA).

The tile size tells MeqTrees how many timeslots to digest at once. Visibility data are processed in time/frequency 'tiles', the default shape of these includes all frequency channels and a number of time slots specified by the value in the options.

You can select a range of frequency channels with the next option.

Finally you can ask MeqTrees to read in any information about bad data which have been flagged out, if the Measurement Set contains such a table. These simulations don't, so this can be left deactivated.

Ignore the 'make an image' option for now, we'll come to that in a little while.

Don't click 'view MS' just yet, though.
