Data for 'Correlated insulator at the surface of the polar metal Ca3Ru2O7'

Underpinning data for the main figures in the manuscript. Data have been acquired using low energy electron diffraction, angular-resolved photoemission and scanning tunneling microscopy. Data are provided as text files, images or as Igor Binary Wave files. Text files can be opened with a normal text editor, images are provided as TIFF files that can be opened with most image processing tools. The angle-resolved photoemission spectroscopy data was acquired at the Bloch beam line of the Max-IV synchrotron. It is array-like data. The raw data is provided in Igor Binary Wave format, which can be loaded using the Igor Pro software or e.g. the open source peaks python package.
