J/A+A/363/440       BR photometry of Abell 2104              (Liang+, 2000)

Probing the gravitational potential of a nearby lensing cluster Abell 2104. Liang H., Lemonon L., Valtchanov I., Pierre M., Soucail G. <Astron. Astrophys. 363, 440 (2000)> =2000A&A...363..440L
ADC_Keywords: Clusters, galaxy ; Redshifts ; Photometry Keywords: galaxies: clusters: general - galaxies: clusters: individual: A 2104 - cosmology: dark matter - cosmology: gravitational lensing Abstract: The cluster Abell 2104 is one of the lowest redshift clusters (z=0.153) known to have a gravitational lensing arc. We present detailed analysis of the cluster properties such as the gravitational potential using the X-ray data from ROSAT (HRI) and ASCA, as well as optical imaging and spectroscopic data from the CFHT.

Note (1): Galaxy positions were determined from the R image and should have an accuracy of ∼0.7" rms. Note (2): Presence of emission lines: 102: Hβ, Hα, [N II], [S II] 117: Hβ, [O III], Hα, [N II], [S II] 214 Hβ, Hα 313 Hβ, Hα, [N II], [S II] 320 He I, Hα, [N II], [S II] 214 [O II], [O III], Hβ, Hα, [N II], [S II] Note (3): This parameter is related to the correlation coefficient Ccorr by the formula DVmag=k/(1+Ccorr) where k∼870km/s was determined by the Tonry and Davis (1979AJ.....84.1511T) method. Note (4): Redshift measurement quality: 1: highest peak in the correlation function and checked by hand 2: highest peak in the correlation function but unable to be checked by hand.
