bpsetwt - modifies rays' weights
setwt uses an IRAF-compatible parameter interface.
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.
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.
The value to apply to the rays' weights.
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).
setwt is used to modify the weights of rays in a ray stream.
