Tables providing parameters of the fundamental QPO and its harmonic for the (snapshots of the) NICER observations studied in our paper on the 2023 outburst of Swift J1727.7–1613 (Stiele & Kong, A&A, 2024). This X-ray transient was first detected on 24 August 2023 by Swift/BAT and INTEGRAL. We investigated data from the Neutron star Interior Composition Explorer (NICER) and the Neil Gehrels Swift Observatory taken between August and October 2023.In the paper we present diagnostic diagrams and investigated the evolution of quasi-periodic oscillations (QPOs) and the evolution of the spectral parameters.The overall evolution of Swift J1727.7–1613 is consistent with a low-mass black hole X-ray binary transiting from the low-hard state through the intermediate states into the high-soft state. Based on the Lense-Thirring precession interpretation of type-C QPOs we obtained outer radii for the hot inner flow and found that the overall evolution of these radii agrees well with the evolution of the inner disc radii obtained from fits to the energy spectra. This result holds on all times scales tested in this study and supports the Lense-Thirring precession interpretation of type-C QPOs.
