Short term stabilities of a bunch of quartz oscillators.

I had posted this some time ago but this is an updated version.

In answer to Ulrich's earlier question on the FTS 1200 #1 I retested it
in

the same setup as the FTS1200 #2 and it still showed the results 

below. The Piezos are the 10811 clones. The Motorola units are 

The large can units you sometimes see on eBay. The DOXO is the

clone of the Oscilloquartz dual oven 8663.
