-The beam computed at 150GHz, at a location offset by 10cm in the X (=co-scan) direction is now also available.
+The beam computed at 150GHz, at a location offset by 10cm in the X (=co-scan) direction is now also available, on top of the central beam and Y=10cm beams generated earlier this month.\\

 Two different effects are now visible on the power spectra:
-  * an overall rotation of the polarization by ~1.73 deg, showing up as a strong EE to BB leakage when the full IQU beam is used instead of assuming a copolar beam (something we did **not** see in the (X,Y)=(0,0) and (0,10cm) cases)
+  * an overall rotation of the polarization by 1.74 deg, showing up as a strong EE to BB leakage when the full IQU beam is used instead of assuming a copolar beam (something we did **not** see in the (X,Y)=(0,0) and (0,10cm) cases)
   * the ell-dependent leakage from EE to BB seen previously is now larger than before.
