cal jumps aug05


    The Tsys for sbw jumped from 34K to 24K around 18aug05. This was the same time that the refrigerator was being worked on.  On 18aug05 the receiver log says that the cal cables were replaced. The plots show the sbw system performace during 2005 (ps) (.pdf):

It looks like the cal value injected in the sbw dewar has changed around the 18th of august05. We probably need to remeasure the cal values.
