TH

The TH command defines a Top Hat beam. The syntax is:

TH weight waistx waisty decenterx decentery

Note that the data values are separated by spaces. The weight value defines the dimensionless relative total power of this beam as compared to other beams in the same ZMM file. The weight value may be negative, for details, search the help files for "Using random values". The other values are exactly as defined for the Top Hat beam, search the help files for "Top Hat" for a description. The transverse data values, such as the waist and aperture sizes, may be scaled from the POP Beam Definition tab; search the help files for "Using the scale factor" for details.
