Evolution of spectral parameters, fitting NICER spectra with an absorbed disc blackbody and Comptonisation model. Given parameters are (from top to bottom): foreground absorption, inner disc temperature, inner disc radius, photon index, nthcomp normalisation, and reduced χ2. The electron temperature is not shown as it is not well constrained.
