Well it's OK. It seems out of place inserted between sec2.2 and 2.4. Also it
would be better if the equations explicitly included the averaging over many
pseudo-realizations of noise.
I say include this in ref response and not in the paper. Then include it in
the next paper where it can be made to fit in better - this paper is basically
about beam systematics.

Hi,
I've added a longish section to the systematics paper, S2.3, that deals
with the referee's demands regarding noise model discussion. I think it's
too long, but I'd like to hear comments, especially from John and Clem.
Some of this can go in the private response instead of the paper itself.

We might want to do that as well (for B3). It is unclear to me why we have (at
least sometimes) in the past tried to align the x/y of the detector grid with
horizon/vertical?

The noise in TT is not much worse than the noise in EE&BB - it's absolutely
tiny compared to the signal. If we got the noise debias wrong by factor 10
then this test against Planck would likely still pass.
However the ref's concerns are misplaced - we may unfashionably stick to using
auto spectra but noise de-bias misestimation is demonstrably not a major
problem.

Hi Colin,
I think you were there today when we discussed the desire to do finer el steps
for B3 given the smaller beam size. Walt suggested interleaving cycles of
schedules offset by 0.125 deg which seems like a good solution - allows to bin
the data either way and makes for minimal change versus previous practice.
But it then occurred to me that we should do the same for Keck given that we
now have 220GHz receivers whose beam size is very similar to the B3 95GHz
beams.
Looks like we are right now coming to the end of the 2nd cycle of dk angles.
Please remind me what the length of the current sequence is. We should do the
next sequence with 0.125 deg offset in el.
Anyone who objects should chime in - I *think* this makes sense.
Best,
Clem

Please explain what you mean a bit - not sure I follow.

Hi,
Here is the systematics paper referee report. It's a bit harsh, and it
seems to be written by a former QUIET person. In the end it's positive,
though.
There are three main gripes, which I'll quote:
1. The role and significance of the Jackknife failures
>
I dispute we have jackknife failures.
2. A detailed description of the noise model used in both the determination
> of the
>
auto-spectra and the null tests, in particular the role of correlations in
> the effective noise
>
I think it's a fair criticism that our noise debias uncertaintiy is nowhere
quantitatively invoked. We can include a number for noise debias
uncertainty using high ell scan jack, or even the cross correlation with
our T maps as a funciton of ell with the Planck T maps, which is 1 to
really really high precision. Incorrect noise debias would make this number
less than one.
3. Resolution of the apparent systematic discrepancy between the B2
> auto-spectra and
> the B2/Keck cross-spectra in Figure 9 of the Results Paper
>
Should be easy enough to reference the Keck paper.
I'll get this going in a google doc.

Hi all,
Here is an invitation to "Cosmology on Safari" from Cynthia, open to any
appropriate BICEP2 or Keck'er who may be able to attend--contact your
local PI or the talks committee if you are interested. Looks awesome,
but unfortunate timing for many of us who will be tied up with Pole
activities in January.

Hi John,
Good to hear from you, and sorry to hear about the unfortunate timing
with Pole deployments! I've heard that from a few other people as
well. We'd certainly love to have anyone who's available from BICEP2
and Keck. If all goes well with this conference, we hope to make it a
regular event every other year, so perhaps we'll see you at some other
point. (And we may choose slightly different wording re: rhinos in
future advertisements!)
cheers,
Cynthia

==========================================================
Dear colleagues,
We would like to invite you to a workshop "Cosmology with the CMB and its
Polarization" to be held in downtown Minneapolis next January 14-17
(Wednesday-Saturday), and sponsored by our Fine Institute for Theoretical
Physics. The purpose of the workshop is to assemble the US and international
CMB community to assess the current status of experimental and theoretical
studies, and to look forward to the future.
The workshop will start with several presentations on the full mission Planck
results to be announced this fall. There will then be a comprehensive review
of the status of ground based and sub-orbital experimental programs, and of
current theoretical aspects. We will also have a report on the upcoming
European M4 proposal for a post-Planck space mission and a discussion about
NASA's plans for CMB and participation in M4. The workshop will end with a
meeting of those interested in the next generation CMB S4 polarization project
recently endorsed by the US P5 HEP advisory committee. With all the current
activity in the field it should be an exciting meeting!
The meeting will be held in the Marquette Hotel in downtown Minneapolis which
is connected to the Skyway system giving easy indoor access to many other
hotels and restaurants etc.
Thanks to the sponsorship of FTPI there will be no registration fee. Please
register your interest in attending the workshop at the following website:
http://www.ftpi.umn.edu/workshops/2014-2015/cmb2015
Due to limited space, and to ensure a balance of participants, we will need to
approve registrations. Talks are by invitation only although suggestions and
contributed posters are both very welcome.
Best Regards,
Clem, Keith, Marco and Shaul
P.S. We apologize if you receive multiple copies of this message. Likewise
please forward this message to relevant collaboration mailing lists and any
other colleagues who may be interested.
