Table 2

Velocity values in km s-1 as derived from the 847 keV 56Co line fits in four epochs shown in Fig. 3, and listed in Table 1.

Time Bulk Spread

16.3–41.3 –6920 ± 1480 5060 ± 1330
41.3–66.3 1600 ± 1720 3940 ± 1260
66.3–99.1 1600 ± 1600 7250 ± 1560
134.8–164.0 –80 ± 1870 4570 ± 1840

Notes. The 1238 keV line derived centroid and spread are only determined in brightest epoch 3, and are 5050 ± 1240 and 4290 ± 1370 km s-1. Fixing the 1238 keV line’s width to the value determined from the 847 keV line, its centroid also for the weak epoch (4) can be found, at 1610 ± 960 km s-1.
