  We have measured the angular auto-correlation function of near-infrared
galaxies in SERVS+DeepDrill, the Spitzer Extragalactic Representative Volume
Survey and its follow-up survey of the Deep Drilling Fields, in three large
fields totalling over 20 sq. deg on the sky, observed in two bands centred on
3.6 and 4.5 micron. We performed this analysis on the full sample as well as on
sources selected by [3.6]-[4.5] colour in order to probe clustering for
different redshift regimes. We estimated the spatial correlation strength as
well, using the redshift distribution from S-COSMOS with the same source
selection. The strongest clustering was found for our bluest subsample, with
z~0.7, which has the narrowest redshift distribution of all our subsamples. We
compare these estimates to previous results from the literature, but also to
estimates derived from mock samples, selected in the same way as the
observational data, using deep light-cones generated from the SHARK
semi-analytical model of galaxy formation. For all simulated (sub)samples we
find a slightly steeper slope than for the corresponding observed ones, but the
spatial clustering length is comparable in most cases.
