Subject: Re: L1 Conf and old data

For the record, I was actually talking to Bob today about the L1 Cal
coverage as function of time and we came up with the following:

       Period              trigger list         L1 eta coverage
------------------------------------------------------------------
ancient time - 8 May 2002       v6              0.8
8 May 2002 - 26 July 2002       v7              0.8 up to ~ June, then 2.4
26 July 2002 - 30 Oct 2002      v8              2.4
30 Oct 2002 - 7 Jan 2003        v9              2.4
7 Jan 2003 - 27 March 2003      v10             2.4
27 March - 18 July 2003         v11             3.2
18 July 2003 - now              v12             3.2
------------------------------------------------------------------

Cheers,

Brigitte
