dear 6by9 thank you for sharing your work!

I use the RP HQ Cam (IMX477):

libcamera-raw -t 1000 --ev -10 --awbgains 1.0,1.0 --gain 1.0 --analoggain 1.0 --denoise off --rawfull 1 --shutter 9000 --mode 4056:3040:12:U -o /mnt/rd/test%05d.raw --segment 1

I would like to extract only radiometric information of the camera sensor .raw file.
Basically I want a matrix which exactly shows me the irradiance intensitity of every photocell/pixel.

Which command would you suggest me according to my use case?

I tried something like:

./dcraw -D -6 test0.raw

Cannot decode file test0.raw (https://ufile.io/qh74d895)
