We analyzed the pictures of the ETM and Pcal beam spots taken on 2017/04/11 (Tuesday maintenance) to determine the position of the Pcal beams. The numbers below are the position of the Pcal beams from their nominal position of [ 0, 111.6] mm for upper beam and  [0, -111.6] mm for lower beam. 

Upper Beam [1.1+/-0.3, 1.1+/-0.2]

Lower Beam [-1.1+/-0.2, 1.3+/-0.3]

These numbers are comparable to numbers obtained from the pictures taken few weeks ago - LHO alog # 35347.

P.S. The number reported here are mean values of multiple analysis on multiple pictures  and the number in the attached picture is only one such number and thus may be different.
