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.


ACIS Focal Plane Temperature

For this period, 4 peaks are observed.

SIM Movements

Telemetry

We are starting back toward perihelion, By the end of September we expect new record high temperatures to begin showing up. New violations or new extrema are shown in blue cells. Recurrent problems are tracked here.

Trending

Two analysis this week. First a new item. ACIS bias trends. The bias level was calculated following. Here are 2 examples:

I3

S3


CCDS 0, 2 and 8 are the most extreme.

This Week's regular focus is HRC.

Trends last reported on May 29.
