Science Tools Working Group

We did not meet this week, owing to the GLAST science promotion event at Goddard on the 17th; no URL was available at press time. We will meet next week, and the next Catalog VRVS meeting will be on the 31st.

The current version of ScienceTools remains v7r6p1.

Data products: No news

Databases and related utilities

No news. Tony has asked for details about how the various kinds of data that the Data Catalog/Data Server will keep track of will be accessed and how these data types will relate to each other. Richard, Julie, and I are still really just about to draft something for comment.

Pulsar tools

From James: "James and Masa continued work on the pulsar tools. While refactoring the periodSearch package in order to add support for the A4 tool (the limited blind search FFT tool), they discovered problems with the way the chance probability is computed, specifically that the number of independent trials was not being taken into account. They are partway through correcting that problem and will then continue with the scheduled refactoring and work to support the new FFT tool."

Observation simulation

Max R. has updated PulsarSpectrum to simulate binary pulsars (i.e., pulsars in binary systems - many more timing parameters); I do not know how extensively it has been tested. Unrelated to this update, recent versions of PulsarSpectrum (more recent than in v7r6p1 of the ScienceTools) report an out-of-time-range error for pulsars that could be simulated with v7r6p1. Max is looking into why.

User interface and infrastructure

Jean's JIRA issue about discovering that most of the output from gtlikelihood does not go to stdout has been resolved thanks to James' modifications to st_stream.
