Initial parameters and the χ² values for best-fit models containing different IMBH mass fractions.

Model	c	r_hp (pc)	Absolute	Absolute	Absolute	Reduced ^a	Reduced 40′′)^b

no-IMBH	0.8	12.8	135.61	294.80	537.31	3.36	3.06
1% IMBH	0.7	12.8	99.91	345.52	313.21	2.63	3.80
2% IMBH	0.5	13.4	62.41	271.51	277.95	3.09	2.58
3% IMBH	0.4	13.4	58.93	325.88	654.72	3.61	5.01

Notes.

^(a)

This column is obtained by dividing the sum of absolute χ² on the total number of data points for all three observed profiles.

^(b)

The same as the previous column but for the inner 40′′ region.
