@@ -13 +13 @@
 - CHANGED: Combination: the random walk of the AC satellite offsets is defined per time (1 cm per 10 s) instead of per epoch, so the result no longer depends on the sampling interval (at 5 s the offsets were sqrt(2) noisier per hour)
 - CHANGED: Combination: an AC excluded from the clock datum because of inconsistent code biases is used again only after 12 passing checks in a row (1 hour), not after the first one (a borderline AC changed the clock datum every 5 minutes)
+- CHANGED: Combination: attitude consistency correction dC_att of the clocks reactivated: a yaw angle difference between an AC and the master orbit AC (SSR yaw angle or BNC's attitude model, as selected in 'Attitude') changes the ionosphere-free phase wind-up and thus the AC's clock (lambda_IF * dyaw / 2pi), zero for ACs using the same attitude model
 - ADDED: Combination of APC (SSRA) and CoM (SSRC) streams together: with an ANTEX file the combination is done in the CoM frame, the orbits of the APC streams are converted to CoM; ACs not combined because of a different reference point are reported
 - ADDED: Option 'Reference Signals' (key ssrRefSignals): reference signals of the satellite clocks per GNSS for the combination (AC clock referral, code biases from the Bias SINEX file) and the SSR QC, default IGS Real-Time convention G:1W&2W R:1P&2P E:1C&5Q C:2I&6I J:1C&2L S:1C&5Q, e.g. for a switch of BDS to C1X/C5X or of QZSS to L1/L5
