MS Options — Basic Settings

NRAO Home > CASA > CASA Cookbook and User Reference Manual

7.4.1.1 MS Options — Basic Settings

The Basic Settings roll-up is expanded by default. It contains entries similar to those for a raster image (§ 7.3.1.2). Together with the brightness/contrast and colormap adjustment icons on the Mouse Toolbar of the Display Panel, they are especially important for adjusting the color display of your MS.

The available Basic options are:

Data minimum/maximum
This has the same usage as for raster images. Lowering the data maximum will help brighten weaker data values.
Scaling power cycles
This has exactly the same usage as for raster images (see § 7.3.1.2). Again, lowering this value often helps make weaker data visible. If you want to view several fields with very different amplitudes simultaneously, this is typically one of the best adjustments to make early, together with the Colormap fiddling mouse tool, which is on the middle mouse button by default.
Colormap
Greyscale or Hot Metal colormaps are generally good choices for MS data.
