||/P vs. P for NGC 300 ULX1. Solid black lines denote the solution using the W95 approximation while assuming a constant LX. The two solutions based on the derived values from the two data sets (red points) with best statistics (2016 & 2018) presented in Table 1. The Ghosh & Lamb (1979) model prediction is plotted (dotted line) for comparison using the observed 2016 LX. All model lines assume neff = 100%.
