| Radial Temperature Profile of the Cooling Flow Cluster PKS 0745-191 |
|
| Chandra radial temperature profile determined by fitting, in XSPEC, single-temperature spectral models to spectra extracted from elliptical annuli selected to include a minimum of 3000 counts in the 0.29-7.0 keV band. Error bars represent 90% confidence limits. The central cooling in this cluster is clearly evident (Hicks et al. 2002). |
