Title: LISA Science Data Analysis Planning

LISA Science Data Analysis Planning in the

Switzerland LISA LIST Meeting
  • U.S. Project Schedule provides framework for
    Formulation-phase planning.
  • Near-term planning aims for Mission Definition
    Review Feb 2007
  • MDR Objectives have clear implications for LISA
    Science Data Analysis
  • (see Moonis viewgraphs on MDR NASA Success
  • Responsibilities (in the U.S.) during
  • Shared among NASA HQ, LIST, NASA Mission Science
    Office (MSO) , and other areas of the U.S.
    Project (Mission Systems Engineering MSE,
    Mission Ops MO).
  • Products (official Project documents) and
    Activities are stipulated with timelines,
    designated roles for lead responsibility, input,
    review, approval, concurrence.
  • Formulation Products (draft planning in
  • Currently seven proposed documents provided to
    NASA HQ or NASA LISA Project Management (PM),
    from LIST or NASA MS with support from other
    Project Offices
  • Some have precedent from previous NASA missions,
    some are unique to LISA.
  • Formulation Activities (draft planning in
  • Proposed near-term activities in support of
    these products. So far proposal is for work by
    Project MSO. TBD proposals from LIST and LISA
    science community

  • NASA Mission Definition Review (Feb 2007,
    draft products by Oct 2006)
  • Objectives (highlights added)
  • … to confirm that
  • (a) science objectives are fully understood and,
    if feasible, prioritized so as to define
    acceptable descope options,
  • (b) the conceptual system design is tailored to
    efficiently and effectively meet science
  • (c) system-level requirements are traceable to
    science objectives and are clearly and logically
    allocated amongst the independent system
  • (d) the operations concept clearly supports
    achievement of science objectives,
  • (e) technology dependencies are fully defined
    with risks and viable mitigation plans
    identified, and
  • (f) successful execution of the project can be
    reasonably expected within imposed constraints
    and available cost and schedule resources.   "

  • Proposed Formulation Products from Mission
    Science Office
  • Seven official documents
  • 1--3 are standard (with NASA mission
  • 4--5 are new and involve the LIST, and
  • 6--7 are not near-term or not LIST-intensive.
  • 1. Science Requirements Document (SRD)
  • 2. Science Management Plan (SMP)
  • 3. Science Data Management Plan (SDMP)
  • 4. Science Data Flow Architecture Document
  • 5. Science Data Analysis Methods (AMIGOS)
    Development Plan
  • 6. AMIGOS Implementation Plan
  • 7. Education Public Outreach Plan (EPOP)
  • AMIGOS Analysis Methods for Interferometric
    Gravitational-wave Observations in Space

  • Science Requirements Document (SRD)
  • Prepared by the LIST, NASA MSO, ESA PM/MSO.
  • Held by the Project (MSO), Approved by the LIST.
  • Used by the Project to establish the Mission
    Requirements Document (MRD) and impose
    performance requirements on design of the
    constellation and subsystems.
  • Used by HQ as input for the Level One
    Requirements (LOR). HQ provides draft LOR to the
    Project prior to MDR, final LOR prior to SRR/PDR.
    Project must accept final LOR to proceed from
    SRR/PDR. The SRD is revised to reflect the final
    LOR, then accepted by the Project and retained in
    the Project library for reference.

    structure -- constitution and activities of the
    Science Team, locations and organization of the
    Data Centers, proprietary data, AOs for guest

Near-Term AMIGOS Development Activities -1 (from
AMIGOS Development Plan)
n.b. This is brainstorming material presented
for discussion purposes only!
1. Science Data analysis development
activities 1a. Characterization of instrument
science operation and performance 1a1. Develop
procedure(s) for combining multiple TDI
observables to isolate noise contributors 1a2.
Develop test methods to characterize as-flown
instrument noise as it impacts data-analysis,
based on sciencecraft subsystems operations
(levels, spectral shapes, nonstationarity,
non-Gaussian properties). 1a3. Catalog
instrumental noise transfer functions to detect
noise signatures unambiguously in the data. 1b.
Computational infrastructure for data
analysis (Needed for implementation and final
phases and to verify all data-analysis major
milestones.) 1b1. Data storage and delivery
Develop lightweight libraries for use in testing
in final infrastructures. 1b2. Data reduction
and conditioning Implement theoretical model of
low-level measurement in lightweight libraries
for reduction of data sets to level 1B. 1b3.
Source and noise simulators Develop and
validate simulators of LISA science process,
including low-level instrument behavior (gaps,
glitches), and extensive model of the mission
orbits and operations. 1b4. File formats and
data structures Develop extensible data formats
for storage of measured data and for
representation of candidate catalogs of
detections. (continued next slide)
Near-Term AMIGOS Development Activities -2 (from
AMIGOS Development Plan)
  • 1b. Computational infrastructure for data
    analysis (continued)
  • 1b5. Data-analysis application guidelines
    Develop recommendations for LISA application
    software, to enforce traceability and (when
    possible) formal verification.
  • 1b6. Computational resources Develop plan for
    in-house and outsourced capabilities (grid
    integration, etc.).
  • 1b7. Guidelines and protocols for extensive
    testing of data-analysis capabilities and
    milestones This will be accomplished through
    simulation and mock-data challenges. Will
    include evaluation criteria for success of
    contracted activities.
  • 1c. Algorithms and data analysis methods
  • 1c1. Verification binaries Develop and test
    detection and parameter-estimation algorithms for
    known foreground sources. (Algorithms well known
    from LIGO practice.)
  • 1c2. Verification binaries Develop and test
    detection and parameter-estimation algorithms for
    moderately large sets of overlapping but
    resolvable sources. (Algorithms not well
    understood Markov Chain Monte Carlo, Maximum
    Entropy, CLEAN-like algorithms, multitapers
    should be investigated.)
  • 1c3. Verification binaries Develop algorithm to
    infer polarization of gravitational waves from
    multiple TDI observables. (Not known whether 5
    or 6 links are needed,for direct inference.
    Also, TBD whether the "minimum mission" would
    accept polarization inferred over the course of
    one year.
  • 1c4. Periodic sources in the galaxy Develop and
    test detection and parameter-estimation algorithm
    for previously unknown sources in a strong
    background of similar signals.
