Standard Star Monitoring Memo - OLD

Note:

This is the "oldest" version of this memo, when the photometric monitoring was performed with large apertures.

This memo contains photometric information for Proposal 5563 and 6143 which take exposures of the standard star GRW+70D5824 in 9 filters - F160BW, F170W, F218W, F255W, F336W, F439W, F555W, F675W, and F814W - in PC1 and WF3 twice a decontamination cycle. The dates covered in this memo run from 08 Mar. 1994 through 19 Apr. 1995.

The images were calibrated using the WFPC2 pipeline. Aperture photometry was done using a radius of 30 pixels for both PC1 and WF3. The first table contains countrates normalized to the 25 Mar. 1994 countrate. The data on this date was taken 2 days after a decontamination. Note that the CCD's were operating at a temperature of -76° C at this time. A future memo will have the countrates for observations taken at -88° C normalized to a "clean" image at that temperature. The second column is the associated error. The second table contains the measured countrates per second with error.

Please note that the data for 12 Dec and 20 Dec. 1994 were taken with SERIAL clocks 'ON'. This resulted in the actual exposure times for the observations being shorter than the commanded exposure times. PC1 exposure times are 0.250 seconds shorter than commanded while WF3 exposure times are 0.125 seconds shorter than commanded. The countrates have been adjusted to use these exposure times rather than those in the header or the archive. The values for these dates should be treated with some caution.

Decontaminations were done on the following dates:

24 Apr. 1994   23 May  1994   13 Jun. 1994   10 Jul. 1994
28 Jul. 1994   27 Aug. 1994   24 Sep. 1994   20 Oct. 1994
19 Nov. 1994   17 Dec. 1994   12 Jan. 1995   11 Feb. 1995
11 Mar. 1995   07 Apr. 1995
