As a member of the ST ScI's OPUS team, I examined the data and provided the following assessment. A loss of lock occurred during these observations. Lock was not recovered until after the primary observations had completed.
Stars are visible with indication of trailing in the images.
These observations were implemented as observation set N42Q64 in Science Mission Specification 973007B9. The exposure logsheet line that defined them are listed in the following table. The intention of this report is to notify you about shortcomings with the execution of your observations. It is ST ScI policy not to repeat parallel observations.
