Update UT1 - UTC dec06


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. 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 .

    The last fit was done jan06 when the leap second was installed. New data was loaded 07dec06 and refit. The plots show the  Dut1 fit error from the jan06 fit and the new fit (.ps) (.pdf):

    The new  fit  was installed 10dec06 around 20:00 (after the x102)
