Radiation

Quiet.

Detrended CTI

Although we have quoted CTI values of the cleanest data (FT <= -119.7 C, int time > 7000sec), the data fills these conditions are getting rare. From this week, we quote CTI temperature factor corrected ones. The values in the parentheses are CTI based on the cleanest data.

Average of ACIS-I CCDs (MnKa) slope: 1.551e-9 CTI/day (2.270e-9 CTI/day)
Detrended slope: 7.034e-9 CTI/day(7.443e-9 CTI/day)

ACIS Warm Pixels

We display all bad pixels showed up in past, and, if any, previously unknown bad pixels appeared in the last 14 days. We also list hot pixels (defined as 1000 above the average of bias background). Warm columns 509-514 are probably due to a computational artificial effect due to boundaries.

Trending

This week's focus is Gratings.

Trends last reported on Jan 10.

Only the most interesting or representative msids are shown below. For a full listing choose the bulletted link.

Min/max envelopes in dark blue appear on the trending plots. The envelopes are 4th degree fits to the monthly minimum and maximum values for each MSID. The final polynomial form and binning are still being experimented with. We will soon add to the trending pages a report of the fits and predictions they give on future limit violations. The light blue curve is our original smoothing of all the data over 30 day moving boxcars. The green/yellow line is a linear fit to all the data; the break occurs at a limit change.
