LDM-240 Goals for FY15
The LDM-240 goals specified for FY15 under the 02C.04 WBS are:
WBS 02C.04.01 (App framework for catalogs)
- Development in support of use cases utilizing catalog data
WBS 02C.04.03 (PSF Estimation)
- Improved PSF estimation and interpolation (Kriging interpolation)
- Integration of wavefront estimation code into the DM stack
Suggested replanning
"Improved PSF estimation and interpolation (Kriging interpolation)" moved to FY17 and replaced with "Estimation of PSF variation across the full focal plane (single solution)" from FY17.
WBS 02C.04.06 (Object Characterization)
Greedy optimizer for multi-epoch data
- Multi-epoch extended source fits
- Micro-optimized MultiFit model evaluation code
Suggested replanning
Astrometric and Photometric Calibration Pipelines (02C.03.07 & 02C.03.08) are currently assigned to UW in FY18+. DRP will likely need a subset of this functionality much sooner than that. Perhaps we can "adopt" part of those tasks, or encourage the UW folks to reprioritize so that the they are addressed sooner.
HSC work which will be carried out in S15 which we can port to LSST

Outline S15 epics
Rough priority listing:
- Finish measurement framework overhaul
- Deblender
- Galaxy fitting
- Multi-Fit plugin framework
- PSF estimation
- Photometric/astrometric calibration pipelines
We'll likely have to schedule a ~20 SP epic for toolchain enhancements (GitHub migration, etc).
(Strike-through: deferred for this cycle)
| Epic | SP estiamte | Assignees | Note |
|---|---|---|---|
| DM-1910 | 20 | All | Bugs & papercuts bucket |
| DM-1911 | 20 | All | Bugs & papercuts bucket |
| DM-1912 | 20 | All | Bugs & papercuts bucket |
WBS 02C.04.01 (App framework for catalogs)
| Epic | SP estimate | Assignees | Note |
|---|---|---|---|
| DM-1767 | 23 | Bosch (40%), Swinbank (60%) | afw::table improvements; roll-over from DM-1099 + some new work |
| DM-1107 | 38 | Bosch (10%), Swinbank (90%) | Footprint improvements. Rolls over from W15. |
WBS 02C.04.03 (PSF estimation)
| Epic | SP estimate | Likely assignees(s) | Note |
|---|---|---|---|
| DM-1909 | 40 | Swinbank (100%) | PSF estimation |
| ? | Wavefront estimation (deferred unless somebody wants to take this up) |
WBS 02C.04.06 (Object Characterization)
| Epic | SP estimate | Likely assignee(s) | Note |
|---|---|---|---|
| DM-85 | 31 | Bosch (10%) | Rolling over from W15. |
| DM-1907 | 60 | MacArthur (50%), Price (50%) | Porting from HSC and other deblender infrastructure |
| DM-1908 | ? | MacArthur (100%) | LSST deblender development |
| DM-1768/69 | 22 | Gee (70%), Bosch (30%) | Rolled over stores from the W15 measurement framework reworking + some new work. DM-1768 contains low priority miscellanea and doesn't need to be scheduled this cycle, but DM-1769 should be. |
| 30 (provisional) | Gee (100%) | Measurement unit tests. Depends on DM-1102 (SQuaRE). | |
| DM-1108 | 96 | Gee (75%), Bosch (25%) | Galaxy Fitting - Shear Precision Experiments. Needs support from GalSim folks (Krughoff?) |
| DM-1111 | ? | New C++ developer if available | Galaxy Fitting - Micro Optimization. Not essential for our development goals to address this epic in this cycle, but may be necessary to inform hardware choices. Check with Mario. |
| 60 | Bosch | Galaxy Fitting - Sampling Algorithm Plugin | |
| 20 | Bosch | Design MultiFit plugin framework. Rolled over from W15. Depends on updated Butler (or we stub in our own temporary Butler-alike hack, which would be less than ideal). | |
| 50 | Gee | Implement MultiFit plugin framework. |
Total SP allocations
| Name | Availability SPs | Allocated SPs | Note |
|---|---|---|---|
| Bosch | 66 | 58 | Scientist, leader, 0.8 time |
| Gee | 78 | 97 | 0.5 time |
| Lupton | 36 | 10 | 6 SPs per month |
| MacArthur | 126 | 59 + Undefined (deblender) | Scientist |
| Price | 24 | 40 | Scientist, 0.2 time |
| Swinbank | 84 | 98 | Scientist, leader |
| Total | 414 |
Agreed with HSC to split Bosch/Price 80/20 through this cycle.
Dependencies on other groups
SQuaRE: DM-1102, required for our DM-1069.
UW: DM-85. Astrometric & photometric self-calibration (which specific issues do these block?).
Middleware/Butler: DM-1109, multifit, etc.
To Do
- Agree plan for DM-85 with UW group
- Agree plan for DM-1102 with SQuaRE
- Agree plan for astrometry/photometry pipelines with UW group
- Discuss shifting measurement epics to 02C.04.06 with Jeff/Kevin
- What work will be addressed by HSC during S15 that we can claim partial credit for?
- Determine status of wavefront estimation code & consider an epic to integrate that with DM stack (02C.04.03)
- Agree allocation of Price/Bosch with HSC
- Estimate SPs for epics remaining above
- Question for Jeff/Kevin: For epics which we have only started to address in W15, should we close them down and create new epics for S15, or just carry the same epic over?
- Discuss timescale on which DM-1111 is required to inform hardware choices.
