Table 2.
Averaged count rates (in cps) of PN exposures on soft (0.5–6 keV) and hard (6–12 keV) energy bands and hard/soft ratio using 100 s bin light curves.

| 76 | 1.29 ± 0.50 | 0.97 ± 0.27 | 0.73 ± 0.16 | 5.48 |
| 77 | 0.23 ± 0.11 | 0.43 ± 0.18 | 1.77 ± 0.54 | 36.06 |
| 74a | 0.02 ± 0.03 | 0.38 ± 0.29 | 1.01 ± 0.28 | 0.17 |
| 74b | – | – | – | – |
| 74c | – | – | – | – |
| 26 | 1.60 ± 0.45 | 0.69 ± 0.19 | 0.43 ± 0.05 | 8.0 |
| 78 | 2.58 ± 0.41 | 0.80 ± 0.14 | 0.30 ± 0.05 | 0.99 |
| 75 | 1.37 ± 0.46 | 0.64 ± 0.14 | 0.45 ± 0.12 | 2.25 |
Notes. Observations #74b and #74c were not averaged but rather linearly modelled (see text). Local absorption column (NH, in units of 1022 cm−2) is included for comparison. Details on NH spectral fitting are described in Sect. 3.2.
