Science Tools Working Group
The current release version of the Science Tools remains v9r7p1.
Data products: The planned additions to FT2 contents are posted. Warren mentioned today that starting as soon as today FT2 files with 1-second resolution would be available from the Data Catalog. These (or their close cousins) are produced in the L1 pipeline by ft2Util anyway - to feed Gleam spacecraft and attitude information, and turning them into FT2 files was a small additional step. Note - you don't need these at all for your routine analyses but they might be interesting to look at, especially for GRB-type impulsive sources.

No news. Tony made a new release of the Astro Server at SLAC last week; if you had used the Astro Server by that time, you already know about this. The new release fixes bugs in the FITS headers and GTIs of the output. Tony has written a FAQ.
Likelihood analysis
From Jim:
- I implemented the photon and energy flux and error calculations that Jean requested and that were described in my talk at the Monday session of the Collaboration meeting. This is in Likelihood v13r18, pyLikelihood v1r6, and ST HEAD1.686. There is documentation on confluence
- For the DM group, I have implemented a class that will handle multiple likelihood analyses for different regions of the sky simultaneously, tying together the spectral parameters that are expected to be same, i.e., the parameters describing with the dark matter spectrum. The basic idea was outlined by Jan Conrad during the DM splinter meeting. This is in Likelihood v13r18p3, pyLikelihood v1r7, and ST LATEST1.2465

Pulsar tools
From Masa: "As reported last Friday [in an e-mail to some known users], gtbary (v5) has three more parameters for the future implementation of geocentric option. Also, the other pulsar tools that read event files (gtpphase v7r1, gtophase v7r1, gtpsearch v10r1, and gtpspec v10r1) no longer accept an event file that has already been processed by gtbary, in order to mitigate a potential pitfall in a tempo-spectral analysis."

Last week's discussion was about the August source list and associations. Will meet this week.
Science Tools Working Group
The current release version of the Science Tools remains v9r7p1. Reminder: Toby has pointed out that in this release and apparently others since mid-July the packages related to pulsar tools did not compile under Windows. Some other unit tests failed in the Windows builds as well, although these may not indicate fundamental problems.
The current HEAD build (1.683) differs from v9r7p1 primarily in the skymaps and pointlike packages; updates to gtbin and gtrspgen seem to be in the works as well for the next release.
Richard reported that last week SCCS provided 2 RHEL5/gcc4 systems on the farm for the Release Manager to use. RM is not yet making builds for gcc4, however.
The tutorial session on high-level analyses at the collaboration meeting last week was...succcesful. It included a number of how-to presentations.
Data products: The proposed additions to FT2 contents mentioned in the last report are still in progress, with consideration being given to how to set the LAT_MODE column in a useful way - useful for filtering FT1 files, that is.
Databases and related utilities
See the presentations by Tony and Tom S. in the tutorial session mentioned above. Tony described a number of new or updated Data Server services and Tom described features of the FSSC data server, including authentication as a LAT user.

Pulsar tools
From Masa: "The pulsar tools made a major version up for an added feature of ephemeris status reporting. The tools produce warning message(s) when given event file(s) cover a time interval that overlaps with an
ephemeris gap or an exceptional event (such as glitches) in a given pulsar database file. Note that the new feature only gives warning message(s), and the behavior of the tools (such as pulse phase assignment by gtpphase) did not change."

Not sure where this belongs: At the meeting last week Markus and Eric W. presented approaches for studying (measuring) source extent, in the session on Issues on high-level analyses.
No other news, although if you missed it last week you may want to take a look at Gino's presentation on iLAT as a user interface for Web-based analysis

Reminder: Toby has pointed out that in this release and apparently others since mid-July the packages related to pulsar tools did not compile under Windows. Some other unit tests failed in the Windows builds as well, although theses may not indicate fundamental problems.
The current HEAD build (1.682) differs from v9r7p1 primarily in the skymaps and pointlike packages.
I forgot again this week to check with Richard this week about whether SCS has provided RHEL5/gcc4 systems on the farm for the Release Manager to use. I'd assume that no news is no news. In any case, the RM is not making builds for gcc4 and I think we do not yet have a complete set of the external libraries built under gcc4.
The agenda for the tutorial session on high-level analyses for next Monday morning at the collaboration meeting is posted. Please note that this session will be followed in the afternoon by one on on (mostly open) issues for high-level analysis.
Data products: The proposed additions to FT1 and FT2 contents attracted a total of one comment; see here and here. An additional change to FT2 will be proposed, to add a column to include the equivalent of the Run Quality flag. And we expect to start using the already-existing LAT_MODE column. When implemented (you'll get word), these columns will be available for generating GTIs with gtmktime to filter out time ranges by LAT configuration or data quality.

Pulsar tools
From Masa: "As mentioned earlier, we are working on ephemeris status reporting feature, such as warning messages for glitches and timing noise stored in a pulsar database."
Regarding the Windows build problems mentioned above, Masa writes: "I guess they are all caused by the problem reported as the following JIRA issue, although I am not absolutely sure.
https://jira.slac.stanford.edu/browse/STGEN-54
It is fixed with pulsarDb v6r1 as mentioned in my response to the JIRA issue, but the version has another problem. James will be tagging v6r1p1 with the fix, and the problem will go away, I hope."
Aous reported a problem last week running gtpphase in Science Tools v9r7p1. As far as I know this is not resolved, although indications from Eric W. are that although the error message complained about the FT2 file the code may be getting tripped up when the user specifies a list of FT1 files rather than a single FT1 file for the event file input.

User interface and infrastructure (& utilities)
No news, although you may be interested in the command line interface to Hera, the service developed by HEASARC to allow FTOOL and HEASOFT users to run tasks remotely on HEASARC computers. It doesn't have any immediate application for LAT data analysis, but is a noteworthy achievement, and the SSC will be releasing the Standard Analysis Environment Science Tools early next year.
