IRAS

A full set of uncalibrated IRAS (InfraRed Astronomical Satellite) data is stored on an optical disk jukebox at the Space Research Center in Groningen, accessible semi-online through a mail server. The server provides data extraction, calibration, and imaging for survey and Low Resolution Spectral Data. Analysis software (GEISHA) and display software (GIPSY) are used. More interactive access to the database is planned for the future. The system is transportable to other sites. The manual for remote access to the IRAS server can be obtained via e-mail to irasman@sron.rug.nl. An FTP connection allows retrieval of data. Data can be requested by sending e-mail to iras_server@sron.rug.nl. The request can select the data for the area of interest, recalibrate fluxes and position of the infrared measurements, and recombine them into an image. Several options can be set for this processing to obtain the best possible reconstruction of the IR sky for the user's research. The user will be notified when the request is processed, and about how to retrieve the data by FTP. Note that before using the mail server, the user has to pre-register by sending e-mail to irasman@sron.rug.nl. For further questions contact D. Kester, IRAS manager (do@sron.rug.nl or irasman@sron.rug.nl).

The experimental ISSA Postage Stamp Service is available via WWW (http://brando.ipac.caltech.edu:8888/ISSA-PS) and allows to retrieve maps of size 2 x 2 degrees of a user-specified area in all four IRAS bands (12, 25, 60 and 125 microns) with a pixel size of 1.5 arcmin. The maps will be displayed on the screen and can also be retrieved in FITS format for further display and processing.

The IRAS Low Resolution Spectra are available via telnet to hyades.colorado.edu, login as user lrsuser. A more complete set of spectra is available from the University of Calgary. Users should send e-mail to kwok@iras.ucalgary.ca for more information. The 11,000 spectra from the University of Calgary are also available from the CADC via STARCAT (§3.1.3.), including on-line views of the spectra.

Four CD-ROMs with the IRAS Sky Survey Atlas Images were released by IPAC in mid-1992, one each for the three sky coverages HCON-1, HCON-2 and HCON-3, and another one for the average of them. For updated overviews of IRAS data products in general, see a recent issue of the IPAC Newsletter (§3.3.8.). [References: Walker (1991); Roelfsema, Kester, and Wesselius (1993); Wesselius et al. (1992).]
