Phase Windows

Phase Windows consist of an Epoch, a Period, and up to 10 start and stop Phases. Only those bins whose center time is within the specified start and stop phases (for the specified epoch and period) are accepted. Phases' range is from 0 to 1. Phase Windows must be phase ordered (except for the case in which the last window straddles phase 0). Three formats are available to specify the Epoch:

• 1 = d = day ............................ e.g. 123.524268391
• 2 = d s = day and sec .................. e.g. 123 45296.789
• 3 = d h m s ms = day hr min sec msec ... e.g. 123 12 34 56 789

• 1 = d = day ............................ e.g. 0.1234567
• 2 = s = sec ............................ e.g. 10666.659
