by submitting a URL of the form:-
the parameters are as follows:-
and generate images directly in FITS format:-
October 2004: DSS Batch service supports DSS-II requestsThe Digitised Sky Survey batch request service (which allows up to 15 images to be requested at the same time) now supports the second-generation DSS-II service, providing higher-resolution images in three colour bands.
September 2004: PIMMS, WebPIMMS upgraded to v3.6aThe interactive X-ray mission simulator software PIMMS has been upgraded to the latest version v3.6a. This version contains updated XMM-Newton RGS and EPIC effective area curves, in preparation for XMM AO-4. A bug in the model parser has been corrected, now allowing NH to be specified when file-based models are used as second (etc.) components of a composite model.
August 2004: LEDAS staff at eScience meetingLEDAS staff will be attending the e-Science All Hands Meeting at the EMCC, Nottingham from 31st August to 3rd September 2004. PIMMS has been updated to the latest version v3.5. This current release includes Astro-E2 effective area curves, suitable for Cycle 1 proposals. It also includes an XRS-specific routine to estimate the grade fractions.CIAO 3.1) and calibration database (CALDB 2.27) are now available for download from LEDAS. available for download via ChaSeR or anonymous FTP from LEDAS. The long observations have been split so that individual event files are under 2GB in size, but the total data volume including all Level 2 event files is very large (approx. 20GB). Note that analysing these files will take substantial resources in time, storage and compute power.
The latest version of the HEASARC X-ray data reduction/analysis software package HEAsoft (version 5.3.1) is now available for download. HEASoft 5.3.1 contains FTOOLS 5.3.1, fv 4.1.2, XIMAGE 4.2.1, XRONOS 5.21, XSPEC 11.3.1 and XSTAR 2.1k. See the Release Notes for the changes since the last major HEAsoft release (5.3).ARNIE5 database system is now updated on a daily basis using source data from HEASARC. To see the most recently updated tables in ARNIE5, please consult the Catalogue Update page.ARNIE5 database browser has an interactive plotting utility VOPlot, originally written by Persistent Systems under the aegis of the VO-India project. VOPlot has now been upgraded to the latest version v1.2.1 which provides a large number of new options for display and numerical analysis of search results. For more information, see the VOPlot User Guide. Space Telescope Science Institute, LEDAS has now acquired a local copy of the approx. 800GB Digitised Sky Survey II (DSS-II) image archive. This will improve the speed and reliability of queries to the DSS-II image service.ARNIE5 has been significantly enhanced, and now contains 340 catalogues (including the full set of public catalogue data provided by HEASARC). To view the list of catalogues supported by ARNIE5, please visit the ARNIE5 main page.CALDB 2.26) is now available for download from LEDAS.PIMMS has been upgraded to the latest version 3.4a, which includes effective area curves for Chandra Cycle 6 proposals.
The search engine BLASTA now provides access to the Second USNO CCD Astrograph Catalog, a high density, highly accurate, astrometric catalog of 48,366,996 stars covering the sky completely from -90 to +40 degrees in declination. For more information, see the BLASTA UCAC2 help page.
An enhanced version of the Digitised Sky Survey image service now supports the second-generation DSS (DSS-II), providing images in three colour bands, with optional coordinate grid overlays. Users are encouraged to provide feedback and suggestions for enhancements to this new service.
The latest version of the Chandra data reduction software (CIAO 3.0.2) and calibration database (CALDB 2.25) are now available for download from LEDAS. The CIAO 3.0.2 patch version contains bug fixes to the Data Model library, Sherpa and a number of other CIAO tools. It also contains updated proposal tools for the Cycle 6 Call for Proposals.
