2dproj

• name:
  2dproj
• synopsis:

  2dproj inputfile outputfile [-pinhole_distance= value] [-magnification= value] [-inclination= value] [-rotation= value]

• description:
  2dproj does a projection of 3D (x, y, z) data onto a 2D surface using pinhole imaging. The program is slightly nonstandard in that it uses the third column of the mpl-format to store the z values.
• files:
  inputfile is a mpl-format file containing the (x, y, z) values to be projected; the z values are stored in the slot normally used for the y uncertainties. The 2D projection is placed in outputfile.
• options:

  pinhole_distance

  
  Specifies the distance of the pinhole from the (x, y, z) origin. The default is 0, which is interpreted as meaning that the pinhole is at infinity.

  magnification

  
  Specifies the desired magnification of the image.

  inclination

  
  Specifies the inclination of the pinhole above the plane, in degrees. The default is 0.

  rotation

  
  Specifies the angle of view relative to the plane, in degrees. The default is 0.
