August 2000 anneal report for program 8410.

There was an anneal of the CCD on August 27th, 2000, 30 days after the
previous anneal on July 28, 2000. A homogeneous set of data was obtained
from proposal 8410:  The Continuing Monthly Anneal Monitor.

For the most part, previous trends continue. The rate of hot pixel
continues growing within the average of previous months.  The mean 
post-anneal dark count-rate (MPADCR) grew again, contradicting the 
decrease of the previous month. Although the increase of this month
could be indicative of a flattening on the MPADCR, we cannot draw 
any conclusions at the moment.

1) The number of post anneal hot pixels continue increasing consistent
   with the previously determined long term trends. 
 
   > 0.1 e/s: 15471 pixels on August 27 
   > 1.0 e/s:  3146
   > 10. e/s:   354

   > 0.1 e/s: 14875 pixels on July 28 
   > 1.0 e/s:  3016
   > 10. e/s:   337

   > 0.1 e/s: 14539 pixels on June 28
   > 1.0 e/s:  2972
   > 10. e/s:   329

   > 0.1 e/s: 14295 pixels on June 1
   > 1.0 e/s:  2988
   > 10. e/s:   315


2) The *raw* post-anneal dark countrate for this anneal is 0.02424 cts/pixel.
   This compares with 0.02306 cts/pixel in July 28, 2000, and 0.0188 cts/pixel 
   in August 24 1999. 
   
3) The iterated median count rate (after iterating up to 30 times by
   eliminating pixels +/- 5*sigma) is 0.00410, more than last month.
   
4) The creation rates for hot pixels over this period were within the normal
   range

   > 0.1 e/s:  60.1 pixels/day in August 27 2000 
   > 1.0 e/s:  11.1
   > 10  e/s:   1.8

   > 0.1 e/s:  40.2 pixels/day in July 28 2000 
   > 1.0 e/s:   4.4
   > 10  e/s:   0.2

   > 0.1 e/s:  61.8 pixels/day in June 28 2000 
   > 1.0 e/s:   6.9
   > 10  e/s:   0.9

   > 0.1 e/s:  52.2 pixels/day in August 22 1999 
   > 1.0 e/s:   4.7
   > 10  e/s:   0.4


5) The rate at which new hot pixels annealed out  was within the normal range
   of fluctuations.

   > 0.1 e/s: 65.8% annealed away in the August 27 00 anneal.
   > 1.0 e/s: 59.5%
   > 10  e/s: 68.0%

   > 0.1 e/s: 71.2% annealed away in the July 28 00 anneal.
   > 1.0 e/s: 65.4%
   > 10  e/s: -60.0%

   > 0.1 e/s: 84.8% annealed away in the June 28 00 anneal.
   > 1.0 e/s: 108.9%
   > 10  e/s: 39.0%
