Andriaseta Sitraka - Detector configuration comparison
-
CKJ: Can you make a table where in the first column you have the rotation, on the second column 90 m and on the third 20 m, in each cell you could add the number of events. For us will be very easy to visualize the data you analyzed. AS: I’ll do that I’ll upload the slides with the new table.
-
CKJ: Slide 5: Statistical error? AS: Error on the statistics. CKJ: Upstream experiment in and out? GY: Probably yes.
-
DL: Are you applying the neutron selection? AS: No. GY: We are not applying a neutron selection, but something has changed.
-
CM: Did you check the log?GY: We didn’t fill the log with such information. DL: We have something. We can discuss it offline.
-
CKJ: Slide 7: bottom left plot 180 - 180 degree dec 12 - 13 and 13 - 14. What happened to that? GY: We don’t know.
-
DL: I don’t think that with this very basic selection we cannot understand what is going on here. GY: Probably we should clean up the sample.
-
DL: Are you comparing all the runs or some runs during the day? AS: Just some run. GY: Sitraka compared the same day but different runs and she saw no differences.
-
DL: Slide 8: why did you remove the type 3 MPPC? GY: Because they are dominant. DL: Even using 20 PE cut? GY&AS: Yes.
-
CKJ: Why did you change to 180 degrees? GY: Probably we didn’t align well the detector.
-
CKJ: First plot in slide 4 and fourth plot: the difference seems almost exactly the same. We should track down what happened.
