Table 2.

Values for the stellar mass inferred in a spatially integrated fit with BAGPIPES using different star formation history parameterisations.

SFH	log(μM_*/M_⊙)	ΔM_r [dex]
Constant	$9 . 7_{- 0.2}^{+ 0.4}$ $9.7^{+0.4}_{-0.2}$	$0 . 5_{- 0.1}^{+ 0.2}$ $0.5^{+0.2}_{-0.1}$
Exponentially declining	$9 . 7_{- 0.2}^{+ 0.3}$ $9.7^{+0.3}_{-0.2}$	$0 . 5_{- 0.1}^{+ 0.2}$ $0.5^{+0.2}_{-0.1}$
Log-normal	$9 . 7_{- 0.2}^{+ 0.3}$ $9.7^{+0.3}_{-0.2}$	$0 . 5_{- 0.1}^{+ 0.2}$ $0.5^{+0.2}_{-0.1}$
Double-power law	$10 . 4_{- 0.2}^{+ 0.4}$ $10.4^{+0.4}_{-0.2}$	$- 0 . 2_{- 0.2}^{+ 0.3}$ $-0.2^{+0.3}_{-0.2}$

Notes. The mass offset ΔM_r is calculated with respect to the resolved CSFH stellar mass of log(μM_*/M_⊙) = $10 . 2_{- 0.1}^{+ 0.2}$ $10.2^{+0.2}_{-0.1}$ , thus ΔM_r = log $(M_{*}^{resolved})$ $(M_{*}^{\mathrm{resolved}})$ – log $(M_{*}^{integrated})$ $(M_{*}^{\mathrm{integrated}})$ .
