Amount of [CII]-related gas in the Cen A center.

Case	H mass traced by [CII] emission
	outer CND	central CND	outflow

Notes.

^(a)

High-density (n ≫ 3000 cm^-3), high-temperature (T ≫ 91 K) limit yielding minimum total H mass with neutral gas phase carbon abundance.

^(b)

HII mass assuming T = 10⁴ K with elemental carbon abundance x_C = 1.6 × 10^-4.

^(c)

H₂ mass with neutral gas phase carbon abundance .

^(d)

Total gas mass traced by [CII] emission, including helium contribution of 35% by mass.
