Currently:

  • Fairfield extraction software produces data in milliVolts, removing the bit weight.
  • PH5 undoes this operation on ingestion storing the data in raw counts.

Recently (Feb 2020) the NRL includes responses for Fairfield nodes that assume the data has the scaling factor applied as is after the extraction. Thus if data is ingested with ph5 with the scaling factor removed loading the NRL response will be wrong... This has happened.

Propose:
PH5 no longer remove the scaling factor applied on ingestion. Archive the data as it comes off the Fairfield system in mV and use the NRL response.
