Parameters of the two ⁵⁶Co lines as fitted in four epochs shown in Fig. 3.

847 keV line

Time	Flux	Center	Width	Flux	Center	Width

16.3–41.3	2.34	827.2	14.3	0.91	1259.1¹	17.7¹
41.3–66.3	2.74	851.3	11.1	1.11	1259.1¹	17.7¹
66.3–99.1	3.65	851.3	20.4	2.27	1259.1	17.7
134.8–164.0	1.90	846.6	12.9	0.38	1244.9	18.8²

Notes. The time tag is given as the center of the epoch, in days after explosion. Fluxes are given in units of 10^-4 ph cm^-2s^-1, line centroid and width as Gaussian width σ in keV units. Annotations:

⁽¹⁾

value fixed to value fitted in 3rd epoch;

⁽²⁾

value fixed to value fitted for 847 keV line.
