UPDATES

• Use updated version of pfile-tools, which adds the following to the header metadata:
  • mps_r1 - manual prescan R1
  • mps_r2 - manual prescan R2
  • mps_tg -- manual prescan TG
  • mps_frequency -- manual prescan center frequency
  • aps_or_mps -- indicates the type of prescan (0 means using auto prescan, 3 means using manual prescan)

MINOR
