Dataset for "Interplay of crystal thickness and in-plane anisotropy and evolution of quasi-one-dimensional electronic character in ReSe2"

Data associated with paper on ARPES and computational studies of rhenium diselenide. Contains:

- Raman data used to identify number of ReSe2 layers;
- ARPES data on an associated pair of monolayer and bulk-like ReSe2 flakes with the same crystallographic orientation;
- ARPES data on a set of monolayer, bilayer and trilayer ReSe2 flakes with the same crystallographic orientation;
- Input parameters and output projected wavefunctions for modelling the band structure of monolayer ReSe2 using the plane-wave density functional theory code Quantum Espresso.
