AHELP for CIAO 4.11


Context: proposaltools


Tools that aid in the preparation and submission of Chandra proposals


Below we list tools available to help in feasibility studies, proposal preparation, and proposal submission. Refer to the Proposer area of the Chandra X-ray Center web site for links to these tools and the most current proposing information.

Tools that Access the Chandra Observation Catalog Database

To obtain information about observations that have already taken place or have been approved to take place with Chandra, use Web ChaSeR to search the Chandra Data Archive. See the Chandra Archive web pages for more information.

Tools for Assessing Feasibility

The following tools will aid in determining the feasibility of using one of the Chandra detectors to observe a specific target. When appropriately used, they can help provide a reasonable estimate of exposure time.

Proposal Planning Tools

These tools aid in the preparation of a Chandra proposal, in particular: evaluating target visibility and observing constraints, and converting between date/time systems and coordinate systems. These are available either over the web, or through a command-line interface; refer to ahelp files for the individual tools for more information.

Chandra Proposal Submission

Electronic submission of proposal information is required. The scientific justification must also be submitted electronically. Paper copies will be accepted only from individuals without access to the Internet.
