Because the Kepler Survey Field is very large, the easiest way to search for targets of interest is via a positional search. The following are the released PTF fieldid numbers:

        4344        4345        4425        4426        4427        4428
        4505        4506        4507        4508        4581        4582
        4583        4584        4585        4655        4656        4657
        4658        4726        4727        4728        4794
 
Much of the Kepler survey data was taken under unusually good seeing conditions. As a result of this and the detector sampling, in many cases the cosmic ray detector has triggered erroneously on real sources, and those bit masks should be considered cautiously.
