| 54 | | * Bill spent most of this week finding a workaround to the bright star astrometry problem for the STS exposures. After much testing we came up with a recipe that uses stars only stars within a magnitude range where the astrometry is correct for final fitting. In order to get the initial fit close we changed psastro to optionally use different magnitude ranges for the initial grid search. This method was successful. |

| | 54 | * Bill spent most of this week finding a workaround to the bright star astrometry problem for the STS exposures. This involved: |
| | 55 | * studying the addstar implementation getting familiar with how it works. |
| | 56 | * changing the code to (optionally) use different sets of stars for the initial grid search and final fitting |
| | 57 | * Tested using the usual range for grid search and for the fit using stars within a magnitude range where the errors in the astrometry are small. |
| | 58 | * Ran tests of the results in dvo. Created a wiki page showing the results for our test exposures. |
| | 59 | * tested that new code is not use with the usual recipes and integrated into the production tag |
| | 60 | * Started reprocessing the STS.2010 data using the new code. |
