Description

Some test data we ran on the RH-305 system at DSW. I thought the data looked pretty great though so I decided to edit it anyway. Strong gradient in the image since there were no flats (we moved the camera after taking this I am pretty sure) but still somewhat controllable with DBE.

This was processed a while back so there is still some ringing showing up from deconvolution, but I aim to fix that in a future revision.
