Hello,
I am wondering about the properties of possible trails along the readout
axis in ACIS images.
The issue is that in an image we have found what appears to be a real
trail behind a point source, however it is along a column of S3, which is
the readout axis. We're wondering what the expected properties of
instrumental trails are so that we can compare with the data.
The trail is behind a faint but very significant point source and we have
verified that it is not an aspect problem ie the events from the trail are
distributed evenly in time during our 20 ks observation.
