Improve Event Building with EUDAQ2 EventLoader (!145) · Merge requests · Corryvreckan / Corryvreckan

Simon Spannagel requested to merge decode_after_match into master Aug 14, 2019

Initially I set out to remove the requirement to decode M26 data multiple times - I failed. They are packaged within a single subevent and only after decoding reveal their plane numbers and names. So no chance.

Then I decided to at least match the plane name against the current detector (this is the only place where we know which detector this is from, in actual name since the event description contains e.g. NiRawData or CaribouRawData) but this is not possible because the TLU does not define planes and would fall through this raster.

The problem of processing sub-events multiple times is still there, but at least for now relatively academic. Observe this simple example with one M26 detector and one TLU. My (simmplified) config is:

[EventLoaderEUDAQ2]
name = "TLU"
file_name = "run000283_ni_190329095902.raw"

[EventLoaderEUDAQ2]
name = "MIMOSA26_0"
file_name = "run000283_ni_190329095902.raw"

which produces:

Observe how the TluRawData sub-event is processed by both the MIMOSA26_0 instance and the TLU instance of the event loader module (Stored trigger ID 1 at 27915us appears twice in the log).

Below there are a few small fixes, none of which change the functionality apart from removing the sorting-by-name which is not necessary since we add the TLU as separate (auxiliary) detector.

This fixes #55 (closed) This fixes #60 (closed)
