h2. Agenda

h3. Release status

* Current release = 1.0.0

* Targets for release 1.0.1:

** execute_against_data.py should be always make a tarball

** Support for gcc 4.9

** Updates to Geometry handling

** EMR reducer

** Updated tracker noise

** Workbook added 

* Targets for future release:

** Trigger MC

** Fix memory leaks

** Tracker -- Kalman updates

h3. Schedule

* attachment:2015-08-19_MAUS-Schedule.ods

h3. Detectors

* Detector integration (D. Rajaram)

** Reconstruction quality flags (*A. Dobbs* to make requests to detector groups) #1585

* Tracker (P. Kyberd)

** *PRIORITY INTERRUPT* C. Hunt email 18-08-2015:

_"After a lot of playing around, and seeing how the tracker reconstruction correlates to the TOF reconstruction, it seems that the output from the track reconstruction is incorrect and requires a rotation of 120 degrees and a sign flip to correct it.  If you sit and think for a while you can justify this as being the result of the planes being in the wrong order. However as the data is not specifically sensitive to the plane ordering it could be one of 3 things:

- Construction differs to design

- Recon geometry differs to construction

- Mapping differs to construction and recon geometry"_

K. Long keen we pursue as matter of urgency
