Fit Detail for SNR J0519.56902
nH was derived by fitting observed spectrum with two thermal plasma model.
component A:
dominant at inner region
parameters were derived from
bright shell at N
.
Abundance of Olike element was set to zero asumming Typ1 I SN(
Hughes et al., 1995
).
source=(xswabs * xsvraymond)
reduce chi^2 = 7.41398
nh = 0.2283 10^22/cm^2
PARAMETERS
DataSet 1: 153 data points  144 degrees of freedom.
Statistic value = 1067.61
Probability [Qvalue] = 0
Reduced statistic = 7.41398
end
component B:
dominant at outer region
parameters were derived from
clump at NE
.
source=(xswabs * xsvraymond)
reduce chi^2 =
nh = 0.3298 10^22/cm^2
PARAMETERS
DataSet 3: 90 data points  76 degrees of freedom.
Statistic value = 246.296
Probability [Qvalue] = 7.54433e20
Reduced statistic = 3.24074
end
Total:
Total spectrum was fiited with above two component.
Only nH and normaliztion factor was thawed.
Williams et al.(2001)
derived nH=0.22 with vnpshock model.
source=(xswabs * (xsvraymond + xsvraymond))
reduce chi^2 =
nh = 0.2446 10^22/cm^2
PARAMETERS
DataSet 2: 200 data points  197 degrees of freedom.
Statistic value = 3302.85
Probability [Qvalue] = 0
Reduced statistic = 16.7657
end
Total fit with additional component:
For better estimation of flux
source=(xswabs * ((xsvraymond + xsvraymond) + xsraymond))
reduce chi^2 =
nh = 0.2446 10^22/cm^2
PARAMETERS
DataSet 2: 200 data points  199 degrees of freedom.
Statistic value = 3227.76
Probability [Qvalue] = 0
Reduced statistic = 16.2199
