This repository contains the data products from our VLT/UVES deep spectroscopy of Galactic planetary nebulae, Hf 2-2, M 1-42 and NGC 6153, which exhibit high values of abundance discrepancy factor (ADF). The uploaded files include:- Three PDF files ("Hf2-2_1d.pdf", "M1-42_1d.pdf", "NGC6153_1d.pdf") showing the extracted 1D UVES spectra of each nebula. Wavelengths are given in Å, and fluxes are normalized so that F(Hβ) = 100. - A compressed archive "2D.zip" containing the fully calibrated 2D spectra in standard FITS format, organized by object and exposure time (long and short exposures). These FITS files can be read and analysed with common astronomy tools such as Astropy, IRAF/PyRAF, SAOImage DS9, etc.- A compressed archive "NGC6153_PV_diagram.zip" containing PDF figures of position–velocity (PV) diagrams in various nebular lines and related diagnostic maps for NGC 6153. These figures show, for example, line emission, electron temperature and density diagnostics, recombination and charge-exchange corrections, and ADF maps, corresponding to the figures discussed in our paper (Huang et al. 2025, ApJS, in press). The 2D FITS spectra are the primary data products that can be used to reproduce and extend the emission-line measurements and spatially-resolved diagnostic results presented in our paper. The PDF files of the 1D spectra and PV-diagrams provide visual demonstrations for convenience, and are direct links between the UVES data files and the figures in the associated article.
