@ cambion:

AOA1 (ADR1)......2,7deg
AOA2 (ADR2)......2,8deg
AOA3 (DMC1).....5,4deg
IIRC it has to do with the mod (EIS2) status.

For pre-mod all those AOA values are Indicated AOA values.
For the post-mod the AOA3 (DMC) is the sum of Indicated AOA value(ADR) and the Corrected AOA from the IRS.
That is why the result is, in general, a factor of 2.

Reason: to have the (median) Corrected AOA stored on DFDR because in EIS2 this will be the source for BUSS.
