[12:07:22] Robin Corbet joined
[12:07:57] Terri Brandt should these papers just be on LAT data? or also on sources seen with LAT?

[12:08:30] Terri Brandt sounds good!
[12:09:21] Pablo Saz Parkinson yes

[12:14:51] David Smith silence reigns...
[12:14:53] Eric Grove if you're speaking, Patrizia, I can't hear you
[12:14:57] Eric Grove yes
[12:14:57] Andrew Chen better
[12:14:58] David Smith yes
[12:15:21] David Smith wow!
[12:15:35] David Thompson Congratulations to Nanni!
[12:15:38] David Smith For the Green Party?
[12:15:41] Andrea De Luca joined
[12:16:18] Eric Grove you're a bit fain,t Andrew
[12:17:47] Eric Grove

[12:22:52] Andrea De Luca joined
[12:24:54] Andrea De Luca left
[12:32:57] Andrew Chen nominally E>100 MeV, photons run out at high energy
[12:33:09] Andrew Chen I would say that there's a lot of contamination from photons 100 MeV
[12:33:50] Roger Romani joined
[12:34:28] Seth Digel What does contamination from photons 100 MeV mean?
[12:36:12] Paul Ray joined
[12:36:19] Pablo Saz Parkinson I think the question was for Andrew
[12:36:32] Andrew Chen dE/E ~ 1
[12:36:47] Andrew Chen for steep spectra, think analogue of Eddington bias
[12:37:00] Seth Digel Ah, ok
[12:37:39] Seth Digel The color bar in that figure goes from 0 to 0.6 counts cm-2 s-1 pixel-1
[12:39:13] Tyrel Johnson joined
[12:39:19] Joshua Lande left
[12:39:26] Joshua Lande joined
[12:39:44] Rolf Buehler joined
[12:40:22] David Smith Jurgen is apparently in Tuirkey
[12:41:16] Rolf Buehler left
[12:42:03] Seth Digel Pub Board has approved resubmitting the paper on July 24, not sure if it has gone back in yet
[12:42:07] Eric Grove https://confluence.slac.stanford.edu/display/SCIGRPS/UnID+Fermi+Objects+Suzaku+paper
[12:42:47] Joshua Lande left
[12:43:00] Joshua Lande joined
[12:47:28] David Smith The draft of the "Two Nancay" (PSRs J2017+0603 and J2302+4442...
[12:48:02] Michael Wolff Coming soon...
[12:49:50] David Smith Personally i don't really see that it matters... once they're in the hands of referees, all synchronisation gets lost.
[12:49:52] Paul Ray I don't think submission is the important thing.
[12:50:06] David Smith We don't post to astro-ph before acceptance anyway.
[12:50:15] Paul Ray Go ahead and submit any of them when ready.
[12:50:19] David Smith I vote: submit a.s.a.p.
[12:50:27] Paul Ray We'll coordinate on re-submission timescales
[12:51:01] David Smith Paul's remark is wise. (as usual)
[12:51:09] Paul Ray If you submit the Suzaku paper it will put more pressure on Scott as well.  
[12:51:18] David Smith verily.
[12:51:27] Teddy Cheung thanks
[12:51:32] David Smith yes
[12:51:42] Paul Ray left
[12:51:46] Eric Grove https://confluence.slac.stanford.edu/download/attachments/12222500/J1103-53-100727-GlctEVO.pdf?version=1&modificationDate=1280246396148
[12:52:02] Paul Ray joined
[12:52:36] Paul Ray Scott Ransom just wrote back to me that he is working on it now and expects to have a draft for me today.
[12:53:29] Eric Grove thanks Paul. Good news, that.
[12:56:00] Joshua Lande left
[12:56:08] Joshua Lande joined
[13:00:18] Jean Ballet left
[13:05:47] Roger Romani So... we are to conclude that the gamma-ray source is the Blazar and the MSP is just seredipitous?
[13:06:09] Eric Grove yes
[13:06:35] Damien Parent what is the Edot of this MSP ?
[13:06:38] Pablo Saz Parkinson I don't think it had been associated with an AGN when it was selected
[13:06:59] Peter den Hartog do you detect a source adding all the data after nov, and if so what spectrum does that give?
[13:07:08] Michael Wolff left
[13:07:56] Paul Ray The best test will be to look for pulsed emission once we have a good timing ephemeris from the radio
[13:08:01] Peter den Hartog ok, thanks!
[13:08:36] Damien Parent do you have an idea about the distance / Edot ?
[13:08:54] Robin Corbet left
[13:08:59] Paul Ray Not off the top of my head. 
[13:09:01] Ozlem Celik Paul?
[13:09:04] Paul Ray It is in the paper draft
[13:09:07] Damien Parent ok
[13:09:13] Paul Ray we have a DM and the distance is quite large I recall
[13:09:17] Paul Ray maybe 5-6 kpc?
[13:09:36] Paul Ray I think it would be one of the most distant Fermi MSPs if we detect it
[13:09:36] Aous Abdo left
[13:09:58] Paul Ray Oh, so my memory was totally wrong! 
[13:10:02] Paul Ray Not too surprising...
[13:10:08] Peter den Hartog cool stuff
