Retain partial optical detector waveforms in the reconstruction files
Closed this issue · 4 comments
As part of the plan to reduce the storage requirements of ICARUS data, optical detector waveforms are being dropped from Stage1 (and possibly Stage0) output.
Given that this loss is effectively irreversible due to the costs involved in processing the data again, there is desire to retain at least part of that information for future improvements.
The gamble is to write information that may be useful in the future, without knowing exactly which developments may utilise it.
Several proposals have been made, including:
- retain an interval for each reconstructed hit
- retain an interval for each reconstructed flash
- retain the full waveform information only around the beam gate
- discretise the waveforms into a new data product
Whatever is decided, it needs to be deployed before ICARUS Run2 data processing starts.
Is this possibly another use case for ChannelROI?
Fixed by #478 (I think ... in part at least ...)
PR #478 implements option 3 (retain the full waveform information only around the beam gate), but it does not change the standard workflow to use the new feature.
Resolved by #504.
