Notes from the 2 May 2014 meeting of the simulations group.

Attendance was taken by asking all people on the phone to log on to the HipChat simulations room.  This mechanism worked fairly well.  Those who were not able to log on to the chat room were able to indicate their presence by voice.  Please update the list if I missed anyone.

Attendees : Jim C., Srini, Mario, Lynne, Richard, Chris W., Steve R., Cathy, Kem, Kirk G., Michael, Debbie, Heather, Peter, Simon

Breakout suggestions:

Title: Systems Engineering Integrated System Database
Description: This is a meeting to talk about how to build a database that can contain and version all the
information needed to describe the LSST system. There will be interfaces so that all subsystems of the
project can use the same parameterization of the overall LSST system.
Organizer: AJC
Number of hours needed: 3
Who: Representative from simulations (opsim/phosim/catsim), systems engineering, camera, data management,
telescope
How many: 15
Constraints on schedule: None

Title: Applications of PhoSim for Wavefront Sensing & Optical Performance Simulation
Description:
Organizer: JRP
Number of hours needed: 2
Who: phosim, wave front sensing team, camera, T&S, DM
How many: 15
Constraints on schedule: None

Title: Applications of PhoSim for Sensor Simulation
Description:
Organizer: JRP
Number of hours needed: 2
Who: PhoSim, Sensor, Camera, DM
How many: 15
Constraints on schedule: None

Title: PhoSim Science Applications & Tutorial
Description: There was a question about whether the time allotted is enough. From Debbie's experience 2 hrs
is just enough time to get up and running. Anything more will require more time.
Organizer: JRP
Number of hours needed: 2
Who: PhoSim, DM, Science collaboration members
How many: 25
Constraints on schedule: None

Title: Bridging the gap between algorithm development simulations and DM
Description: There is a lot of work going on simulating simulator effects and on the algorithms to correct for
them. Much of this work is outside of DM, but the algorithms will inform DM and results from DM processing
will feed back into algorithm development and simulation fidelity. What is the process for directing the
feedback between these three systems?
Organizer: I'm putting Chris Walter down since he brought it up.
Number of hours needed: 3
Who: Camera, PhoSim, DM, Others working on algorithm development
How many: 10
Constraints on schedule: None

Title: Integration of DM CameraGeom into other work
Description: Many subsystems need to know about they layout of the camera relative to other coordinate systems
(pixels, focal plane, pupil). DM has worked on solving the problem of mapping from one system to another and
others may be interested in making use of this work.
Organizer: KSK
Number of hours needed: 2
Who: CatSim, PhoSim, Camera, DM
How many: 10
Constraints on schedule: None

Title: Development requirements on project wide models (Sky, sensor properties, cloud, etc.)<U+2028>Description:
Description: There are many models in use in different simulation efforts (cloud, sky, sensor), but currently
none of them have project wide implementations. This breakout will discuss the models that need to be project
controlled and what the interfaces are for those models. We do not intend to discuss the implementation of
the models.
Organizer: KSK or Lynne Jones
Number of hours needed: 3
Who: PhoSim, CalSim, CatSim, DM, Camera
How many: 15
Constraints on schedule: None

Title: PhoSim Users Group
Description: Complimentary to the other PhoSim users meeting, this breakout will be an introduction to the
PhoSim users group as well as provide a venue for sharing results aquired by using the PhoSim
Organizer: Kirk Gilmore, Debbie Bard
Number of hours needed: 3
Who: PhoSim, CatSim, Science Collaboration
How many: 20
Constraints on schedule: Broadcast at wide scientific audience.

Title: MAF breakout; Tutorial
Description: There is an intro session on Monday morning. Should there be another breakout?
Organizer: Lynne Jones
Number of hours: 3
Who: Science Collaboration,
How Many: 15
Constraints on schedule: None

Title: Dealing with data from test instruments at Cerro Pachon an Cerro Tololo
Description: Functionally, how do we handle taking the data. What interfaces need to
be in place to be able to use the data that come from instruments installed on the summit?
Organizer: Chuck?, Lynne?
Number of hours needed: 2
Who: PhoSim, DM, Simulations, T&S
How many: 10
Constraints on schedule: None

Title: Incorporating the Sky (and cloud?) Camera into Simulations Models
Description: This is may be included in the previous breakout. Not only does the data need to make it into
the hands of the people how can use it, but it also needs to be incorporated into models.
How do we use these data to simulate calibrations and do the end to end tests validated by data from
the test instruments?
Organizer: MWV, T&S, Lynne (someone else?)
Number of hours needed: 3
Who: System Engineering, T&S, PhoSim, CalSim, DM,
How many: 10-15?
Constraints: After the breakout that discusses the functional aspects of taking the test instrument data.
