Quiet
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. We quote CTI temperature factor corrected ones. The values in the parentheses are CTI based on the cleanest data.

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.

Only the most interesting or representative msids are shown below.

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.
