5{\textbackslash},\{{\textbackslash}rm deg\}{\textasciicircum}2\$ in two of the most well-studied extragalactic legacy
fields (COSMOS and XMM-LSS), we measure the galaxy stellar mass function
(GSMF) between \$0.1 {\textless} z {\textless} 2.0\$. We explore in detail the effect of
two source extraction methods (SExtractor and ProFound) in addition to
the inclusion/exclusion of Spitzer IRAC 3.6 and 4.5\${\textbackslash}mu\$m photometry
when measuring the GSMF. We find that including IRAC data reduces the
number of massive (\${\textbackslash}log\_\{10\}(M/M\_{\textbackslash}odot) {\textgreater} 11.25\$) galaxies found due
to improved photometric redshift accuracy, but has little effect on the
more numerous lower-mass galaxies. We fit the resultant GSMFs with
double Schechter functions down to \${\textbackslash}log\_\{10\}(M/M\_{\textbackslash}odot)\$ = 7.75 (9.75)
at z = 0.1 (2.0) and find that the choice of source extraction software
has no significant effect on the derived best-fit parameters. However,
the choice of methodology used to correct for the Eddington bias has a
larger impact on the high-mass end of the GSMF, which can partly explain
the spread in derived \$M{\textasciicircum}*\$ values from previous studies. Using an
empirical correction to model the intrinsic GSMF, we find evidence for
an evolving characteristic stellar mass with \${\textbackslash}delta
{\textbackslash}log\_\{10\}(M{\textasciicircum}*/M\_{\textbackslash}odot)/{\textbackslash}delta z\$ = \$-0.16{\textbackslash}pm0.05 {\textbackslash}, (-0.11{\textbackslash}pm0.05)\$,
when using SExtractor (ProFound). We argue that with widely quenched
star formation rates in massive galaxies at low redshift (\$z{\textless}0.5\$),
additional growth via mergers is required in order to sustain such an
evolution to a higher characteristic mass.},
