Table 7.
Best fit Ni Kα parameter values for 2000 (left) and 2014 (right) spectra.
| Parameter | 2000 | 2014 | 
|---|---|---|
| N (1047 ph s−1) |  | 3600 (f) | 
| E (keV) |  | 7.47 (f) | 
| σv (km s−1) |  | 7000 (f) | 
| ΔC | 130 | 440 | 
Notes. The 2014 parameter values could not be constrained, so we fixed (f) them to their initial fitted values.
