For the mira variable RT Bootis the GCVS 4 gives these elements:
Max = (24)42722 + 273,86 * E
My analysis gives that these elements are no longer valid; the maxima
now occur about 150 d "too early" - more than half the period. A
better expression for the star's variation is given by:
Max = (24)46754 + 268,49 * E , valid from about 1970.
For further details, see an article at my web site:
