Rework scan_info/channel_info/data_info
Talking to @sebastien.petitdemange there is some stuff to be fixed in the data reception.
Current state
- A
scan_info
is published before the devices are prepared - A
new_child
which is not really useful to be used - A
data_info
which is supposed to be published together with the data- which is not reachable by Flint
Rework
It would be good to provide:
-
scan_info
, containing structural information for the scan- That's already done, that's fine
-
channel_info
, containing structure information for a channel (after the preparation of each devices)- There is AFAIK no API from a channel/acquisition-device to expose that
-
data_info
, containing metadata per data- This is not exposed right now
TODO
-
Provide a clear state of this aspect from the scan acquisition
