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.
