wedge
wedge - simulate a wedge-shaped aperture
wedge uses the standard parameter interface.
-
input
file
-
The input ray stream. If it is the string
stdin, the
UNIX standard input stream is used.
-
output
filename
-
The output ray stream. If it is the string
stdout, the
UNIX standard output stream is used.
-
theta_min
float
-
-
theta_max
float
-
These specify the angle of the wedge and its angular position. Both
numbers are in degrees.
-
xcent float
-
-
ycent float
-
These specify the coordinates of the center of the wedge. Both
numbers are in millimeters.
-
z float
-
The wedge's position along the optical axis, in millimeters.
-
reject boolean
-
Whether the wedge should reject rays which pass through it, or
accept them.
-
version
boolean
-
Print out wedge's version and exit.
-
debug
list
-
A list of debug flags. None are presently defined.
wedge simulates a wedge shaped aperture. The sides of the wedge
are of infinite length. It can either accept the rays which pass
through the specified angles, or it can reject those, and accept
all other rays (via the
reject
) parameter.
At present there are four programs which masquerade as wedge;
the degeneracy is due to different ray formats.
- wedge and wedge_phot read and write djphot format rays.
- wedge_fr reads and writes fullray format rays.
- wedge_bpipe reads and writes bpipe format rays.
All versions use the same parameter file, wedge.par.Eventually wedge will be the same as wedge_bpipe.
