NAME

photz - set the Z coordinate of rays


DESCRIPTION

photz simply sets the Z coordinate of the rays in a ray stream to the specified value. Its main use is after the SAOfocus routine, which resets the Z coordinate to a number that you probably don't want.


PARAMETERS

photz uses an IRAF-compatible parameter interface.

input
The input bpipe ray stream to process. If it is the string stdin, it reads from the standard input stream.

output
the destination for the output rays. if it is the string stdout, it writes to the standard output stream. It writes bpipe formatted rays

z
