Abstract

We report a comprehensive Cu

bond directions (
a
and

) in the
CuO

planes. We confirm the strong in-plane anisotropy of the 2D charge correlations and observe their symmetric response to pressure: pressure along
a
enhances correlations along
b
, and vice versa. Our results imply that the underlying order parameter is uniaxial. In contrast, 3D long-range charge order is only observed along
b
in response to compression along
a
. Spectroscopic RXS measurements show that the 3D charge order resides exclusively in the
CuO
2
planes and may thus be generic to the cuprates. We discuss implications of these results for models of electronic nematicity and for the interplay between charge order and superconductivity.
