That's a great news!
But please be aware that those data are extremely anisotropic. The ones
below the detector are partially absorbed by the experimental table.
Your refinement must take this into account!

We managed to remove the detector and consequently all the instrument noise
using the same procedure. Remarkable effect - absolutely noiseless images.
We call it the Adjusted Pixel Readout Index Linked effect.
There must be an Ig prize in this.

Subject: Re: [ccp4bb] Paired refinement proves data quality goes beyond the
spatial limits of the detector
That is awesome. It means we can add data up to a kilometer out, and
start modelling quarks?
I urge the community to deposit all raw data to a virtual detector of
1km in size - I'm sure Google will happily stump up for the storage
costs, the business case is unarguable.

Dear colleagues,
We, the developers of a program for paired refinement, have found a remarkable
feature that should be shared with the community. The fact that data beyond the
arbitrary cutoff may cause an improvement of electron density and make your
models better is generally accepted. We found now that the data beyond the
dimensions of the detector are still useful, should be used in refinement,
deposited in your structure factor file and if possible, made publicly
available in data repositories as well! This leads us to a general
recommendation, please deposit your raw data including regions beyond the
detector edge or better the corner. Share the maximum available and be FAIR.
Stay safe, best regards,
Petr
