Tools to Aid in Proposal Preparation
- WebChaSeR: Web-based Chandra Search and Retrieval Tool
- ChaSeR: Chandra Search and Retrieval Tool
- Target Lists and Schedules
- CSCView to access the Chandra Source Catalog (CSC)
- CSC interface to Sky in Google Earth
- PIMMS for web-based count-rate and flux predictions (including ACIS pileup). PIMMS helpfile.
- Alternative PIMMS command-line version from HEASARC .
- MARX the Chandra data simulator. MARX FAQ/Features
- Sherpa, the CIAO spectral
analysis and simulation
package.
Read the Sherpa simulations threads. - CIAO the Chandra data analysis package
- XSPEC the HEASARC spectral analysis and simulation package
- WebSpec the web version of XSPEC
- Chandra Instruments Response Files for SIMULATIONS ONLY
- Observation Visualizer (ObsVis) allows the inspection of sky images with overlaid instrument fields-of-view (FoV). Included as part of the latest CIAO package.
- PRoVis interactively plots Chandra spacecraft pitch, roll and visibility by date for any celestial target.
- Optional CCDs instructions on how to specify optional CCDs for ACIS observations
- MaxExpo page
allows estimation of the maximum uninterrupted exposure
time for a target observed at a given pitch angle by
season.
- Orbits page lists projected estimates of usable orbit intervals (and their unusable complement during the radiation zone), for observations which must be tightly constrained.
- Spectrum Visualization Tool displays where spectral features fall on the ACIS-S detector as a function of Y-offset and source redshift.
- Colden calculates galactic neutral hydrogen density. Colden Helpfile
- Precess precesses celestial coordinates (note that cookies must be on in your browser.) Precess Helpfile
- Dates performs date conversions. Dates Helpfile
- Other useful proposal helpfiles:
Overview of proposal tools
Coordinate systems used in proposal tools
Timescales used in proposal tools - The above routines form the Proposal Toolkit and can be run over the web or downloaded as command line tools, part of the latest CIAO package.
