ACIS Warm Pixels

A format of ACIS Bad Pixel List was updated. It now displays all bad pixels showed up in past, and, if any, previously unknown bad pixels appeared in the last 14 days. Because of a bug in the previous version, we could not get hot pixels.In this version, we now have a list of hot pixels (defined as 1000 above the average of bias background), if there are flickering hot pixels, the list show them, too. Although we list warm columns, columns 509-514 are probably due to a computational artificial effect due to boundaries.

There are a few format changes in the following table.

Recent Observations

"Prob" means that there was probably bad time data included in the manual runs. This will be corrected in future processing.
