2 - Wiring and Spectra mapping

Status

pending

Context

Wiring tables is a concept that still exists however the format is now different (.csv as opposed to the old wiring table format).

The options that we’re considering are:

  • change .csv to align with the old format

  • write a service/script to convert to/from .csv

  • keep the two formats separate, acknowledging that they will not be backwards or forwards compatible

Spectra files share the above considerations as they also use a different file format.

Grouping spectra in hardware was primarily used to get around limitations of DAE hardware. In event mode there is no advantage to grouping spectra in hardware.

Decision

We are not going to support the old-style spectra files or any spectrum mapping/grouping in general

For wiring tables this is TBD in https://github.com/ISISComputingGroup/DataStreaming/issues/27.

Consequences

  • If HRPD-x previously grouped spectra in hardware, they will now need to be grouped in software (e.g. Mantid) instead.

  • Our data streaming software will not need to support spectrum grouping.
