Update UT1 - UTC


Intro  top

    UT1 - UTC  (DUT1) is used to convert from UTC  to UT1. This is needed for pointing the telescope.  The Earth orientation dept. of the USNO publishes the measured and predicted values for DUT1. There is usually about 1 year of data available.
    A fit is  done to the "future"  values and then used for the pointing. It is stored in the file : /home/online/vw/etc/Pnt/utcToUt1.dat .
Plots of the fit residuals show:
