Re: puzzlin Chandra proposal thread

The confidence limits should be on the value determined by the fit.

In this thread after running fit_counts if you list the parameters:

isis> list_par;
phabs(1)*(powerlaw(1)+gauss(1))
 idx  param             tie-to  freeze         value         min         max
  1  phabs(1).nH            0     1             0.32           0      100000  
10^22
  2  powerlaw(1).norm       0     1            0.047           0       1e+10  
  3  powerlaw(1).PhoIndex   0     1             1.85          -2           9  
  4  gauss(1).area          0     0     1.503894e-07           0           1  
photons/s/cm^2
  5  gauss(1).center        0     1            12.13           0           0  A
  6  gauss(1).sigma         0     1             0.08           0           1  A


so the value of the parameter is 1.5e-7 and the confidence limits are 
0 and 2.6e-5.  Doesn't that mean that the value is consistent with 0?
