Re: BDraft outline for Science Case of BPol Proposal 

Dear colleagues:

Please find below a proposed outline for the Science Case sections for the
BPOL proposal which I offer as a basis for discussion and for the
organization of the preparation of a draft proposal. Carlo and Paolo have
distributed similar proposed outlines for the foreground and instrument
working groups. I would like to solicit volunteers for smaller groups to
prepare drafts for each of the numbered sections for the Science Working
Group meeting to be held at the end of October) as reported in the
previous E-mail from myself, Carlo Burigana and Paolo De Bernardis.

The call for proposals for the Phase A studies within the framework of
ESA's Cosmic Vision will, we are told, might be announced (following the
special SPC meeting in late September), with a deadline for final
submission likely to fall toward the end of this calendar year or the
beginning of the next calendar year. Based on similar proposals in the
past, we might envisage the science case part of the proposal comprising
some 35 pages or so. Some adjustments may be required once of the
announcement of opportunity is made public.

May I concretely ask you to to send me a short e-mail by
the 13 September :

(1). Stating your
       Name :
       Institution :
       E-mail :
       Areas of expertise :

so that we may compile and post a list of Science Working
Group members.

(2). Any comments or suggestions for modification of the
draft outline below, so that we may finalize it as
a basis for the draft document to be discussed at the
meeting at the end of October.

(3). Please indicate for which sections of the outline
below you are willing to participate in the preparation of
a draft document.

           ********************************

At the end of the day next Wednesday I will compile the responses and post
them on the web. If need be, we can call a telecon to discuss the outline
and the distribution of tasks. I have also set up GNU Mailman distribution
list/archive for facilitate communication within and between the three
BPol working groups and will sent you the details at that time.

I look forward to hearing from you. 

Best regards
