      <description descriptionType="Abstract">Spectrometer files taken with an Andor Shamrock 750 spectrograph and an Andor iKon M CCD. The package contains all raw experimental data used in our paper "Artificial Gauge Fields and Dimensions in a Polariton Hofstadter Ladder" (https://arxiv.org/abs/2506.13521). The files can be read using the python repository "sifreader".</description>
      <description descriptionType="Other">The Würzburg group acknowledges financial support by the German Research Foundation (DFG) under Germany's Excellence Strategy-EXC2147 "ct.qmat" (project id 390858490) and within the project KL3124/3.1. T.C.H.L. was supported by the Singapore Ministry of Education (MOE) grant (MOE-MOET32023-0003) "Quantum Geometric Advantage".</description>
