Quiet
Although we prefer to quote CTI values of the cleanest data (FT <= -119.7 C, int time > 7000sec), the data that fulfills these conditions are getting rare. We now quote CTI based on temperature corrected data for Focal plane temperature <= -118.5 C).
The unit is now CTI/year not CTI/day.
| Average of ACIS-I CCDs (MnKa) slope: | 1.650e-6 CTI/year | (4.520e-9 CTI/day) |

| Detrended slope: | 1.553e-6 CTI/year | (4.255e-9 CTI/day) |
We display all bad pixels that have 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 boundaries.
New definitions of warm pixels and flickering pixels (May 15, 2014). If a pixel displays the level beyond a threshold for more than 70% of the time in the past two weeks, the pixel is categorized as a "warm" pixel. If a pixel is above the threshold more than 30% of time but less than 70% of the time in the past two weeks, the pixel is categorized as a "flickering" pixel.

Weekly focal plane temperature with sun angle and altitude overplotted. Sun angle is the solar array angle, that is the angle between the sun and the optical axis (+X axis). Altitude varies from 10 kkm to 138 kkm.

This week's focus is Ground Computed Gradients..
Last reported on
SEP 18.
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.
