mesh_trans - move the mesh module about a rectangular grid, pushing rays through at
each position.
mesh_trans [param=value ...]
mesh_trans uses an IRAF-compatible parameter interface. A template parameter file is
in /proj/axaf/simul/lib/uparm/mesh_trans.par.
- rayfile
-
The input ray stream. If it is the string stdin, the UNIX standard input
stream is used.
- output
-
The output file stream. If it is the string stdout, the UNIX standard
output stream is used.
- pinhole
-
Pinhole diameter in millimeters.
- xpinhole
-
Absolute X position for the center of the aperture.
- ypinhole
-
Absolute Y position for the center of the aperture.
- zpinhole
-
Absolute Z position of the aperture in millimeters.
- bplate boolean
-
Insert the blocking plate between the aperture plate and the FPC mesh. If
yes, it offsets the blocking plate aperture zbplate mm in front of zmesh.
- zbplate
-
Absolute Z position of the front of the 37mm diameter blocking plate
aperture. Suggested value is 7.1mm, from B. Wargelin 971215.
- xmesh
-
Absolute X position for the center of the mesh grid.
- ymesh
-
Absolute Y position for the center of the mesh grid.
- zmesh
-
Absolute Z position of the mesh in millimeters.
- nhorizwire
-
Number of horizontal wires in the mesh.
- nvertiwire
-
Number of vertical wires in the mesh.
- wirethickness
-
Mesh wire thickness in millimeters.
- hperiod
-
Horizontal period of the mesh.
- vperiod
-
Vertical period of the mesh.
- stepsize
-
Mesh grid step size in millimeters.
- abssize
-
Number of grid sites on a side of the grid pattern. Note that the grid is a
square.
- clean boolean
-
Remove all temporary files when done.
- verbose boolean
-
Send piped commands to the Unix standard error stream.
- help boolean
-
Print this help information.
- version boolean
-
Print version to the Unix standard output stream and exit.
mesh_trans begins by projecting the input rays through a circluar aperture, radius = pinhole / 2, centered at X = xcent, Y = ycent, and Z = zpinhole. The resulting rays are saved to disk in the working directory. The
temporary rayfile is passed through the mesh module
abssize by absize times, centered at each of the positions on the specified grid.
Access to the following parameter files is needed aperture, mesh,
phot2bpipe, projray_bpipe, and tot_wt_bpipe. For local copies, type mesh_trans_setup.
