      Description

      This RFC requests that the proposal described in LDM-513 be adopted into the DM baseline plan. From LDM-513:

      Most catalog measurements produced in a LSST Data Release Production will be derived from pixel values that have been deblended – we have apportioned the flux in each pixel to each of the Objects that overlap that pixel. These deblended pixels values are thus a critical link in our provenance chain, and should be provided to users as a first-class data product. This document provides further justification for the proposal to add this data product and provides a preliminary estimate of the impact on data storage requirements of an additional 83 TB in DR1 and 221 TB in DR11.

      We request that the TCT approve the science case described in LDM-513 and verify the calculations described in the document.

      Once approved, we have to decide whether LSE-163 (DPDD) and LSE-61 (DMSR) should be updated to match.

      Kian-Tat Lim has calculated the cost impact and will report below.
