AST.ZERO_LOWHITS

Reduces spurious large scale structure in the final map in regions containing few data samples

Description:

Using ast.zero_lowhits causes the map to be forced to zero in regions where the number of samples falling in each pixel is less than ast.zero_lowhits times the mean number of samples per pixel, averaged over the map. A value of zero means that no masking of low hits regions is performed. The mask is updated on each iteration. [0]
