namaste tanmoy, Indeed it is true that a few of the yogatArA-s (going by their mainstream identification) will lie outside their boundaries - in which case, any resultant problem (with regards to ritual timing or astrology) should be solved by other means (some people propose alternate identifications for such yogatArA-s). But in most of the cases, no such problem arises. In either case, careful practitioners of the tradition do not give up on current observations.
