2MAPPS version 1.0 is operational. Preliminary analysis of
Northern Survey Facility Data (image products,
photometric and astrometric accuracy for point and extended sources)
gives every indication that they will meet Level 1 Science Requirements.
Caveat is that data from a relatively small number of nights have been
examined in detail, and efforts have been directed to supporting observatory
integration and checkout, so very little can be determined about performance
of system in a broad range of conditions.
2MAPPS v1.0 supporting continued Telescope/Camera
engineering, providing rapid turnaround System Health Monitoring
and small amount of Survey Production Processing.
Currently in intensive period of pipeline parameter
optimization, data analysis and Q/A system maturation.
Pipeline runtime is currently 3.5 x realtime.
Expect to achieve runtime goal of < 2.4 x realtime (to allow
processing of one average night in 24 hours, through removal of
copius diagnostic i/o, optimized compilation, and
cpu upgrade path in processing systems.
IPAC has personnel and is on schedule and budget to fully
support Survey Data Processing and Operations in February 1998
(north) and April 1998 (south).
Development is underway for basic Database System for
2MASS data validation, analysis, final product generation, and
eventually community access. Budget in place for minimal
system.
Additional funding is being sought at NASA HQ for high
performance Database system to support community's 2MASS needs, as well
as IPAC's long-term role as NASA IRSARC.
Recent Milestones
2/5/97 2MAPPS Ver. 1.0p Subsystems delivered
2 month I&T using Prototype Camera data.
Culminated with successful end-to-end "dry-run"
processing of full night of "pseudo" 3-channel data
4/19-21/97 First 3-channel Survey Camera/Telescope data
received and processed to images and source lists.
4/25/97 Detailed engineering reports on camera/telescope
performance provided to Observatory.
5-7/97 Pipeline processing and analysis of 2MASS-North
engineering and nominal survey data. Data
products meet Level 1 Science Requirements for
limited range of conditions tested.
7/1/97 24hr Telescope/Camera System Health Monitor
operational.
2MAPPS Schedule
thru 1/31/98 Support continued Northern Telescope/Camera
engineering and minimal survey operations.
Tape validation/archiving (operational)
24hr System Health Monitor (operational)
Basic photometric Q/A (expected 8/3/97)
4/97-1/98 Intensive Pipeline analysis, parameter tuning, and
Q/A System development. Note that this period is
reduced from 15 months after receipt of Survey
Camera data per original schedule.
7/28/97 NASA ERB Observatory Ops Readiness Review
12/97-4/98 Support commissioning of Southern 2MASS
facility.
