The LWS instrument team has examined the potential impact on all observations and determined during which observations the wheel was not positioned correctly. There are three different cases that can be distinguished:
The tables below give the observations falling in categories 2 and 3. Table 1 lists the observations (TDT, Observer ID, Proposal ID, AOT and Target) for all observations in category 2, together with the amount of obscuration due to vignetting that was calculated for this observation. Table 2 lists all the observations in category 3 (TDT, Observer ID, Proposal ID, AOT and Target) that have been recommended for rescheduling.
