At ING, these files will be updated and checked by ING staff before handing the intrument over to you.

If you are at all unsure about these files when the instrument has been handed over to you, check them:

  • If you have the correct lext.startup, the parameters Nx and Ny should both be set to 2148.
  • If you have the correct lext.set, the parameter Detector should be set to LOR1.
  • If you have the correct readim.proc, the comment header should indicate that the file is to be used for LOR1.
