Deviation in Time Between Equinoxes 1800-2050

  I recomputed the deviations for the time between Spring Equinoxes using MICA data from 1800 to 2050 which was all that was available.

The data appears to be fairly random but there may be a beat frequency present since the data shows very little variation about 1820 and 1990. The mean value was 365.242358 days.
