I've started documenting this at the wiki:

Is that a good enough description for you?
Added:
- IQ balance correction
- Laurent C1 pulse
We are below the target threshold.
Great achievement!
Is it consistent over the whole 900 band, i.e. is that the worst case?
Overall measurements are close (either above or below) to 1.5/5 for
the 900 band in general. 945 MHz is currently the best case, but that
is the frequency I spent the most time on with calibration. Do we need
to be consistently below 1.5/5 or just close?
I guess in 1800 band we're above the threshold
yet. Could you measure
by how much we're off there?
At 1945 MHz,the best I could do was roughly 2.3/7.2 with IQ balance
and LO leakage corrections. I didn't try any 1800 band frequencies.
