NAME

bpsetwt - modifies rays' weights


PARAMETERS

setwt uses an IRAF-compatible parameter interface.

input

This parameter specifies the name of the bpipe format input ray file. If the filename is the string stdin, it reads the UNIX standard input stream.

output

This parameter specifies the name of the output ray file. If the filename is the string stdout, it writes to the UNIX standard output stream.

operand

The value to apply to the rays' weights.

op

The operator which applies the operand to the weight. It may be one of add, sub, mul, div, or eq (as the parameter inteface is stupid and cannot handle extra =, -, or + characters on the command line).


DESCRIPTION

setwt is used to modify the weights of rays in a ray stream.
