The temperature map is shown in Figure 5a. Temperature
variations are within a factor of 3 across the whole image and within a
factor 1.7 considering only the spatial bins with acceptable 
values. These variations are statistically significant
being larger than the fit uncertainties (see table 2). The
temperature map reflects the different nature of the X-ray spectra of
different regions in the field of view as already reported in Figure 2
of Paper I. The bins with acceptable values of have
temperatures in the range 0.15-0.25 keV (
K), which
correspond to a shock speed of 350-450 km
sec
(see Eq. 1). The
spatial bins with high
are mostly concentrated in sectors a to d
(e.g. a4, a6, b5, d3). We have verified that a 2T CIE model
provides always a good fit to the observed spectra in the latter cases,
in agreement with the results already found in Paper I.
