Fits to the observations using a NLTE one zone emission code. Top: April and bottom: May spectra. The red lines indicate the mean model. The orange shaded band shows the 95% credibility region. Ion contributions are shown in blue ([Fe II]), green ([Co II]) and magenta ([Ni II]). The atmospheric absorption bands shortwards of 1.12, 1.48 and 1.915 μm are shaded grey. The resulting values for the temperature and electron density for April spectrum are 3700 ± 400 K and 2.18 (±0.56) × 105 cm−3 and 3300 ± 200 K and 1.69 (±0.59) × 105 cm−3.
