Dear Colleagues,

Tell us about your XMM-Newton publications and PR activities

We encourage the community to inform the XMM-Newton Helpdesk (email: xmmhelp@sciops.esa.int) about all the papers publishing XMM-Newton data. This will allow us to link the observations in the XMM-Newton Science Archive with the related publications.

Please, be reminded that all publications which make use of XMM-Newton data must include the following acknowledgment:

"This work is based on observations obtained with XMM-Newton, an ESA science mission with instruments and contributions directly funded by ESA Member States and the USA (NASA)."

In addition, the Project Scientist would appreciate to be informed via email (fjansen@astro.estec.esa.nl) about all planned press releases and other public relation activities which are related to XMM-Newton.

We thank you very much in advance for your attention and help on this subject.

Clarification: Naming conventions for sources found by individual researchers

It has been spotted by the the IAU "Clearing House" of Commission 5 Working Group on Designations that there is a modification needed in the proposed naming convention for the XMM-Newton sources detected by individual researchers:

It should have been XMMU JHHMMSS.s+/-DDMMSS and *** NOT *** XMMUJ HHMMSS.s+/-DDMMSS

    source position: RA 03 10 15.1, Dec -76 51 31.2 (J2000)
    recommended acronym: XMMU J031015.1-765131

    source position: RA 17 23 48.7, Dec +82 17 33.8 (J2000)
    recommended acronym: XMMU J172348.7+821733

The coordinates for the designation are "truncated" and not "rounded".
XMMU is intended to be used for those serendipitous sources which need to be referenced in a paper.

For work involving exploitation of the full set of serendipitously detected sources in one or multiple XMM-Newton fields we recommend the XMMAA, XMMAAA, etc. approach. Here AA or AAA represent the authors' initials, and should be used for large interim surveys provided that the authors have submitted their acronym to the Acronym Registry (for further details see the IAU Specifications for Nomenclature web page at http://cdsweb.u-strasbg.fr/iau-spec.html).

The discussion on how to name OM detected sources is still ongoing with the "Clearing House" members. For the time being we propose to name them XAU JHHMMSS.s+/-DDMMSS to distinguish them from XMM-Newton sources detected in X-rays.

Target of Opportunity Notification Page

The XMM-Newton SOC has released to the public now its Target of Opportunity (ToO) Notification Web Page which is available at;

This page forms the unique interface for the submission of all ToO proposals. The proposer will need to enter important target information which is further used to validate the request. The page also informs about the terms of reference which do apply for the proposal evaluation, data reduction and publication.

SAS status & RGS calibration problem

The further development and maintenance of the XMM-Newton Science Analysis System (SAS) is continuing at high pace. Significant updates of the tasks and calibrations have been implemented. Testing is ongoing to make the SAS ready for the next public release (SAS 5.1) which currently is foreseen for June 2001.

In order to prepare for the intermediate SAS release to be used by the Processing Pipeline Subsystem (PPS), for some time, the combination of SAS 5.0 with the calibration files RGS1_CROSSPSF_0002.CCF and RGS2_CROSSPSF_0002.CCF was used. This created inappropriate selection regions on the cross-dispersion versus dispersion plane.

It has been decided by the project scientist that this was not serious enough to justify to hold the release of the products. Due to many changes in the calibrations of RGS over that period, the user is advised anyhow to re-run the processing and extract new spectra with most recent calibration files.

The Survey Science Center (SSC) has provided a list of obs-id's where RGS spatial images extraction regions in the PPS products were strangely defined. Of the 171 product sets delivered to the SOC so far 96 are affected. The attached list of observation IDs is that of product sets delivered by the SSC to the SOC in which the product *CALIND* includes the filenames RGS?_CROSSPSF_0002.CCF, i.e. those affected by use of the incorrect calibration files.

To be informed of the periodic updates to the CCF (Current Calibration Files) you might consider subscribing to the CCF mailing list (http://xmm.esac.esa.int/mailman/listinfo/ccf/). You can visit the list archives at http://xmm.esac.esa.int/pipermail/ccf/, too.

XMM-Newton data CD-ROM production

The production of the CD-ROMs containing XMM-Newton data (ODFs and PPS products) is fully operational. At the time of this bulletin, 164 CD-ROMs have already been shipped to the corresponding observation PIs.

The goal is to ship CD-ROMs to the PIs within 30 days from the observation.

For all the observations performed later than February 16 2001, CD-ROMs are produced on a real-time line. Earlier observations are being reprocessed in a dedicated back-up production line. The reprocessing will be completed within a few months.

XMM-Newton Science Archive (XSA)

The first version of the XMM-Newton Science Archive (XSA) will be online at the time when the data rights for the first GT observations will have expired (March 2002).

In the meanwhile, SAS scientific validation datasets are accessible through the URL: http://xmm.esac.esa.int/public/xmm_sas_sv_top.html.

With best regards,
The XMM-Newton User Support Group
