The python utility is called simutil.py, and is located in a scripts directory of your installation.
CASA <> execfile(".../simutil.py")
CASA <> util=simutil()
CASA <> util<TAB>
Methods:
- average_direction(directions) Returns the average of directions as a string, and relative offsets
- calc_pointings(spacing, imsize, cell, direction=None, relmargin=0.5)
If direction is a list, simply returns direction and the number of pointings in it.
Otherwise, returns a hexagonally packed list of pointings separated by spacing and fitting inside an image specified by direction, imsize and cell, and the number of pointings. The hexagonal packing starts with a horizontal row centered on direction, and the other rows alternate being horizontally offset by a half spacing. All of the pointings will be within a rectangle relmargin * spacing smaller than the image on all sides.
