Hello all,

As you may know, we have instituted a new system of reviewing important
ALMA memos relating to calibration (see the attached descriptive email
if not).  Because there are a number of memos which have come out in
the last year or so that fit in this category, we feel it is necessary
to actually attempt to go over these historical memos as well as any
new ones which are appropriate.  You are receiving this email because
you have either specifically been identified as somebody with particular
expertise in one or more of the areas addressed in these historical 
memos, or because you are on one of the relevant ALMA calibration email
lists.  If you are identified specifically below as a potential reviewer
for one of the memos, please let me know if you are willing to accept
this responsibility.  If you are not identified specifically, please
feel free to contribute reviews of any of the memos.

Reviews will be gathered into a centralized location, and the authors
of the memos will be asked to respond to reviews, and perhaps prepare
a revised memo (although neither of these are mandatory).  If the
replies are deemed satisfactory (by the Project Scientists), the memo
will be accepted as an official one for the Calibration group, and
noted as such.  In this way, this set of memos will essentially replace
the project book as the most recent repository of information on
calibration for the ALMA project, at least in the areas which are 
covered.

Here is the list of memos and targeted reviewers, going backward in 
time, along with the list of targeted reviewers:

1 - Memo 423 - The Vane Calibration System revisited
    Guilloteau, 2002May27 (draft)

    (this draft memo may be obtained at:
     http://www.cv.nrao.edu/~awootten/mmaimcal/alma_423.pdf ).

All of these memos except the first (draft) one may be found at the
ALMA memos web page: http://alma.aoc.nrao.edu/memos/index.html .

Again, if you are one of the targeted reviewers, please let me know if
you are willing to do this.  We would hope that you could complete your
review within a month or so.  And, if you are not one of the targeted
reviewers, please feel free to send me a review of any of the above 
memos.
