The problem is still there.
At 6cm the ampls of the cross-correlations of 0X*X,0Y*Y(RT0/MFFE-16) are about 70% lower.

- About the pointing offset of RT0:
  This morning Hans van der Marel had finished to process the data of the pointing observations
  which had been made yesterday. The new pointing grid has been applied in the system(the pointing
  of RT8 has also been improved except RT0). The test observation shows the RT0 works fine now.
  It works fine now at both 6cm and 3.6cm(before there are only 50% of Ampls of cross-correlations
  of 0X*X,0Y*Y, and no Ampls at 3.6cm). Thanks Hans.
