Fit Detail for G029.7-00.2

Central region:

spectrum from Central Region and Outer Shell were simultaneously fitted with common absorption model.
power-law model used for this region.
individual fit for this region gives nH=3.77

source=(xswabs * powlaw1d)
reduce chi^2 =
nh = 3.4337 10^22/cm^2
PARAMETERS

DataSet 1: 379 data points -- 376 degrees of freedom.

Statistic value = 340.047
Probability [Q-value] = 0.908379
Reduced statistic = 0.904381

--end--

Outer Shell:

spectrum from Central Region and Outer Shell were simultaneously fitted with common absorption model.
Two thermal plsama model used for this region.
individual fit for this region gives nH=3.24

source=(xswabs * (xsvraymond + xsvraymond))
reduce chi^2 =
nh = 3.4337
