(This page should ultimately be replaced by a JIRA query against the envisioned future JIRA reimplementation of the change request database, using labels to represent "DM is interested in this". At the moment it is manually maintained.)
Items with a RED state value are ones being considered in the current CCB cycle.
LCR | Title | State | Documents Affected | Comments | Related Issues | CCB meeting for decision |
---|---|---|---|---|---|---|
LCR-908 | Keep all Data Releases loaded in databases | LCR ASSIGNED | LSE-30 (OSS) and many subordinate documents | Adopt the following requirement: "The LSST project shall maintain user access to the contents of all Data Releases. This facility may be provided with reduced performance and capacity for Data Releases older than the most recent one, but be qualitatively identical otherwise." in place of the current policy of maintaining access only to the two most recent data releases. | ||
LCR-900 | DM S17 Mid Cycle Replan | APPROVAL PENDING | Implement S17b plans for NCSA, SQuaRE, and AP with some small tweaks to other subsystems. | |||
LCR-899 | Scheduler Requirements Control | LCR ASSIGNED | LTS-347, possibly LSE-62 | Promote the scheduler requirements in LTS-347 to project-level change control, moving them to an LSE-* document. | ||
LCR-888 | Proposed Meta-data header client for LSST images | LCR ASSIGNED | LSE-72, LDM-230, probably numerous others | Proposes that a common Summit-Base service be created that extracts all observation metadata (from published telemetry or the EFD) intended to be packaged with the image files, storing an artifact containing all this metadata as "headers" for later retrieval. | Q: Does this have anything to do with the reformatted EFD database? -XW | |
LCR-851 | Update to LSE-151 | APPROVAL PENDING | LSE-151 "Interface Control & Compliance Management Process" | Clarifies language surrounding ICDs and documents that describe or actually are the implementations of the interfaces controlled by ICD. | ||
LCR-849 | Update LSE-78 LSST Observatory Network Design | LCR ASSIGNED | LSE-78 | |||
LCR-838 | Auxiliary Telescope Scheduler | LCR ASSIGNED | LTS-187 (draft: SPT-372) | |||
LCR-836 | Typographic correction to LSE-69 to match LSE-130 | APPROVED | LSE-69 | - DM-9336Getting issue details... STATUS | ||
LCR-835 | Camera Heterogeneous Sensor Focal Plane | LCR ASSIGNED | Implicitly sharpens requirements on ability to determine the correct pixel geometry upon data ingest from Camera to DM. | |||
LCR-795 | Updates to DM/EPO interface requirements (LSE-131) | PENDING REFINEMENT | LSE-131 | See substantive discussion in the DM Leadership Team Meeting 2017-03-20. |
| |
LCR-788 | Transfer Task Framework from 02C.07 to 02C.06 | LCR ASSIGNED | (PMCS) | Moves the Task class and a cluster of related classes and interfaces to be a responsibility of the SLAC group. | ||
LCR-787 | Commissioning Re-Plan 2016 | STUDIED | LSE-79 | See also the February 2017 Commissioning Review. Awaiting the report of the review committee. | ||
LCR-786 | Eliminate Base Network Outage Buffer; Expand Summit Camera Image Buffer | APPROVED | Kevin Long is awaiting guidance on what WBS element to use for the additional budget for the enlarged buffer. | |||
LCR-780 | Eliminate Engineering & Facilites Database Copies in Offline Archive Centers | STUDIED | LSE-72, LDM-230 | Requires changing EFD interface with OCS to be the ingest to the Reformatted EFD. | ||
LCR-747 | Unified LSST Authentication and Authorization Services | FULLY IMPLEMENTED | LSE-279 | Provides unified authentication and authorization technical services to assure authorized individuals access LSST services and systems. | ||
LCR-733 | LSST CCD, CCS, and DAQ for the Auxiliary Telescope Spectrograph | APPROVED | LSE-140 and many others | Requires consequential changes to LSE-140 because of the change to direct spectrograph-to-DM image retrieval. The details of the timeline of capabilities required of DM to support the spectrograph, starting 8/2018, remain under analysis. | ||
LCR-687 | Alternate Standard Visit with 30s single exposure | APPROVED | LSE-29 (LSR), LSE-30 (OSS) | Requires that DM be able to handle two types of standard visits: two 15s exposures, or one 30s exposure. Somewhat vague on the question of how closely the two types of visits could be interleaved. | ||
LCR-586 | Update LSE-209 Software to OCS ICD | STUDIED | LSE-209 | A further round of technical updates to the OCS-to-subsystem device interface. The draft already serves as the basis for the prototype and early integration work that is ongoing. |
| |
LCR-581 | Calibration Hardware Requirements Update | FULLY IMPLEMENTED | LSE-30 (OSS), LSE-60, LSE-140 (DM ICD) | |||
LCR-458 | Support for "Deep Drilling" observing scenario | STUDIED |
