Detailed Cycle 12 Proposal Information

Targets Observed and Scheduled with Chandra
Instrument and Observatory Information
Proposal Threads
Count Rate Estimation and Simulators
  • PIMMS Web-based count-rate predictions (including ACIS pileup). PIMMS is part of the Proposal Toolkit, and can be run over the web or downloaded as a command-line program, part of the
    latest CIAO package.
    PIMMS helpfile
  • The Chandra data simulator MARX and MARX FAQ/Features
  • The Chandra data analysis package CIAO can be used to analyze Chandra data. Sherpa, the CIAO spectral analysis package can be used to simulate Chandra spectra.
  • XSPEC XANADU/HEASARC spectral analysis and simulation package
  • WebSpec - the web version of XSPEC
  • Chandra Instruments Response Files for SIMULATIONS ONLY
Useful Proposal Preparation Tools
Observation Visualization and Planning
  • Spectrum Visualization Tool displays where spectral features fall on the ACIS-S detector as a function of Y-offset and source redshift.
  • PRoVis interactively plots Chandra spacecraft pitch, roll and visibility by date for any celestial target.
  • The MaxExpo page allows estimation of the maximum uninterrupted exposure time for a target observed at a given pitch angle by season.
  • The Orbits page lists projected estimates of usable orbit intervals (and their unusable complement during the radiation zone), for observations which must be tightly constrained.
  • Observation Visualizer plots instrument overlays. Included as part of the latest CIAO package.
  • HEASARC's SkyView system (includes ability to download survey data)
Archive and Theory Proposals
  • Proposals to fund archival research on public Chandra data may be submitted. RPS must be used to submit archival proposals. Archival proposals must include a short justification of costs.
  • Proposals to fund theoretical work using public Chandra data may also be submitted. RPS must be used to submit theory proposals. See the CfP for details.
