Suzaku Guest Observer Program: Cycle 4

For US-based astronomers, Suzaku Guest Observer Program, Cycle 4 is an element of ROSES 2008.

Suzaku Cycle 4 Stage 2 is now open.

Suzaku Cycle 4 (Stage 1) is now closed.

For the record:


Suzaku Guest Observer Program: Cycle 5

For US-based astronomers, Suzaku Guest Observer Program, Cycle 5 is an element of ROSES 2009. Further details will be forthcoming.


Technical Description and Planning Tools

Suzaku Technical Description

The Cycle 4 version of the Technical Description is available.

We expect to publish the Cycle 5 in about September, 2009. In the mean time, the Cycle 4 version should be adequate for advanced planning of Cycle 5 proposals.

Planning Tools

The following tools were updated for the preparation of Cycle 4 proposals; updates for Cycle 5 will be made available in Sep/Oct, 2009.

  • For count rate simulations, use PIMMS (the command-line version) or WebPIMMS. PIMMS v3.9h, released on 2008 Oct 20, contains minor updates of the effective area curves of the Suzaku instruments.
    • We recommend proposers to carry out full spectral simulation for HXD feasibility. However, as a first cut, PIMMS v3.9h will provide approximate exposure times necessary for 3- and 5- sigma detections in the standard energy bands using the HXD (1 energy band for the PIN, 2 for the GSO).
  • The XIS response files, XIS blank sky spectra, XIS night Earth spectra, and the HXD response and background files are available for simulation purposes. These (except the XIS night Earth spectra) are also available through WebSpec.
    • XIS night Earth spectra for diffuse sources ("Entire Field of View") have been updated on 2008 Dec 1 to correct a problem with the BACKSCAL keywords.
  • XIS event simulator, xissim, is avialable as part of Suzaku FTOOLS. Read our guide on how to use xissim.
  • When is a target available? Check with Viewing, which is correct for Suzaku. Note that the allowed range of Sun angles for Suzaku observations is 65-110 degrees.
  • Linux and Solaris versions of Maki, a tool to investigate multi-mission observing windows and instrument Fields of View, are available.
  • Coordinate Converter.
  • W3nH - Neutral Hydrogen column density


TOO Requests

Unpredictable events can be observed with Suzaku as targets of opportunity (TOO) in two different ways.


Suzaku Guest Observer Program: Cycle 3

Cycle 3 period (April 2008 - March 2009) is now over. The majority of Cycle 3 GO grants have been issued, although some are still in process.

For the record

Suzaku Guest Observer Program, Cycle 3 was an element of ROSES 2007.


Grant Status and Reporting Requirements

Final Reports for Suzaku Grants

Please note that final reports for Suzaku GO grants are required upon completion of the grant award period. Additional instructions for submitting final grant recipient reports, as well as a required form, can be found here.
