Special Programs | GPDF: Is ToO considered a part of special programs or a category? It is not WFD but unlike other SPs, which are planned, it is unplanned. MLG: The WFD does cover the GP. DDF is also in the WFD area but is considered a SP. A region that is different from the WFD area or that has a different cadence (even if in the WFD area) is considered a special program. A SP wil produce its own data products different from the WFD. Is a SP defined in a programatic sense, e.g observationally or in a data procesing sense, e.g specialized confugurations of the pipeline? EB: The GP in the 2.0 baseline is excluded from WFD - there is a low extinction footprint that excludes all of the plane. Are we talking about scheduler driven proposal IDs as defining SPs or are we saying something about the pipelines? GPDF: Three axes of categorization: by scheduler programme IDs, by type of processing, and by grouping of the resulting data products for user accessibility. MLG: For today's coversation, we will consider SP as observations that result in a separate DP from the WFD DPs. Focus on DM concerns for today.
GPDF: For DDFs, will the same coaddition code as for the WFD work? What different tuning/configuration, etc. is needed to handle deblending, etc. at that depth? RHL: where is the line btw tweaking cfgs v writing specialized code? We've said that we will not do shift-and-stack searches for faint TNOs, yet it's easier to write the loop to do those than to tweak the deblender to go 20 times deeper. GPDF: Whose responsibility is it to deliver? DRP? Where will the human resources come from? Note that we have to make this work anyway at 20yr depth for commissioning and validation purposes, so perhaps we're covered through DR2 - but eventually someone will have to make this work at 100-year depth and beyond. RHL: How much effort will DRP put into configuring pipelines for commissioning/DDFs? JB: need to fine tune params at least to not run out of memory and maintain the same algorithmic behaviour. We'll get data with a large range of depths early on in the survey so need to be able to run the pipelines at a range of depths without requiring custom tuning. GPDF: Calibration of main survey with DDF data is a concern, Will we need to process the DDF data exactly the same as for the WFD? RHL: Process the full 10 and 20yr depth in commissioning. We need to get this far in commissioning. 100/200 yr depth tuning will be a longer term task. Leanne Guy Robert Lupton Follow up to work out where resources will come from to tune pipelines for 10/20 yr depth in commissioning. GPDF: Getting usable metadata to users for DP0.1 has not been a trivial exercise, e.g for out-of-focus data, high-airmass data .. etc. Need to look more at the needed technical capabilities. to transition back to 'in progress'. GPDF to define the work to do after the baseline 2.0 is released. DM-12577 - can fall under user batch/N2D - Gregory Dubois-Felsmann will close this one. For the DM-SST F2F in February. 1) get update on the v2.0 strategy at the F2F - invite Lynne. 2) Keith Bechtol to give a summary of commisisoning data taking plans and a high-level view of the datasets we'll collect. EB: auxtel testing with shorter exposure times with the smaller aperture is progressing. GPDF: Was short exposures flowed down to AP? Does not look like it. EB confirms no testing on simulated 1sec exposures to date Melissa Graham Open ticket to ensure this is flowed down. Done: Shutter open/close : 2sec. Designed to get uniform illumination for 1 sec exposures. reason for "midpointTAI" Leanne Guy to follow un on for effort needed for commissioning. Construction is committed to DDFs so is it the construction project's responsibility to produce a pipeline to process SPs. This will be needed during commissioning. Take to PST/commissioning. Many general concerns on commissioning will getsquished further. Many science drivers for DDFs but not so for many other science | ||
