To be specific--
The current specs are 1 msec minimum integration time autocorrelation and 
16 msec cross correlation, with an average datarate of 3 Mb/s peak 30 Mb/s.
Some details are included on:

Before I have send this, word has come that there has been a helicopter crash 
at the Plateau de Bure with the loss of five lives.  I'm very sorry to hear 
about this. Please accept my sincerest condolences.  

Cieux clairs,
Al
