Abstract (from CDS):

We report on the XMM-Newton observations of the BL Lac object MS 0737.9+7441 during the performance verification phase. A simple power-law fit provides an adequate description of the integrated spectrum in the 0.2-10keV energy band. The photon index is slightly steeper in the EPIC pn data with Γ=(2.38±0.01) compared to the EPIC MOS data (Γ=(2.28±0.01)). The difference is most probably due to the present uncertainties in the calibration of the EPIC MOS and EPIC pn data sets. We report evidence for intrinsic absorption in the distant BL Lac above the Galactic column (N_H, Gal_=3.2x1020cm–2) which is N_H, fit_z=0.315=(2.70±0.20)x1020cm–2 in the EPIC pn data and N_H, fit_z=0.315=(3.25±0.25)x1020cm–2 in the EPIC MOS data assuming neutral gas and solar abundances. The flux variations are found to be of the order of 10%. No significant spectral variability is detected.

within arcsec The VizieR photometry tool allows for easy visualization of photometry points extracted around the Simbad position from photometry-enabled catalogues in VizieR.
The search radius has to be specified by the user. It is currently limited to a maximum of 30 arcsec. It depends mostly on the precision or quality of the coordinates (SIMBAD and VizieR catalogs), the resolution of the images from which the sources were extracted, source extent, and source crowding.
Suggestions are: crowded field: 0.5 to 1.5 arcsec, 3 arcsec otherwise; uncertain coordinates (SIMBAD quality E or coordinates without reference): 5 to 30 arsec (risky!). sed-help-icon
