We still use “WIT” to refer to JWST teams + MESA (+ TEL)

Purpose of MESA
Home of Instrument Engineers
Home of Operations Detector Lab (ODL) Cross-instrument experiments and analysis
Encourage cross-instrument consistency Build on foundation established by WIT
Coordinate WIT working groups
Facilitate communication between scientists and engineers at STScI

WIT Working Group Concept
ParticipantsRepresentative from each WIT instrument group
Lead from WIT, not necessarily MESA
Engineers, once science concept is formulated
Nominal process (still evolving)WG scientists meet and converge on science concept
WG solicits comments from engineers and entire WIT
WG lead finalizes recommendations
Engineers develop engineering concept
WG meets with engineers to finalize unified concept
Engineers generate requirements/PRs
9
WIT Working Group Domains
I&T Coordinate INS support for ISIM ground tests
ETC Fundamental equations, Observing strategies, Science concept for interface (SCAMP)
Proposal Proximity targets, Mosaic tool, Observing template complexity, User support
Operations Coordinate instrument operations working groups,Support onboard script development schedule
Calibration Calibration algorithms, Commissioning activities
Pipeline Pipeline specification and testing, Data products
SID Archive Gather metadata, Prepare data, User interface
Efficiency SODRM, Mechanism use, Overheads, Data volume
Coronagraphy, Backgrounds, Exoplanets, ...

What about Hubble?
HST work in MESAETC, CDBS/CRDS [Rossy]
WFC3 pipeline, HLA source catalogs [Lou]
Cross-Instrument working groupsAstrodrizzle
Enhanced spectroscopy products [Alessandra]
Astrometry?
Cross-Mission ProjectsCDBS CRDS (reference files/data)
OPUS OWL (workflow manager based on Condor)
Define system based on JWST needs and new technology
Implement first for HST, retire risks for JWST deployment
