exclude bad pixels in statistics

current "Statistics" and "show image profiles" does not exclude dead pixels.
Also, current Dead pixel count in "Statistics" counts whole image only, values inside parentheses is for the whole image, not ROI.

Using the scope with multiple PVs

Hello,
Not really an issue, but more a question or a request for an eventual feature
I tested recently your scope, it works very well and with a lot of great functionnalities.
If I understand correctly the scope, it uses PVA with a structure allowing to get more than 1 waveform.

The problem we have, is that we are migrating slowly from CA to PVA, so the QSRV server allowing to get CA and PVA at the same time only produce 1 structure PV = 1 waveform, so in the Channel Field i only get value, and can only display one waveform at the same time.

Is it possible to get more than 1 PV to be able to display them ?

Remark, how do you group your waveform in one structure if the waveforms are the results of different application all along the accelerator ?

Thanks

Hi,

The system I'm using has epics-base v 7.0.8 installed.

Any pointers appreciated.

Thanks,
