Notes. The table is ordered according to the observation date.

(a)

JD-2 450 000.

(b)

The veiling obtained with the SPIRou data at different wavelengths is listed in Table 4.

(c)

We used the convention of positive equivalent width for emission lines and negative values for absorption lines. The equivalent width errors are 0.02 Å for the Hα and Paβ lines, 0.03 Å for the Hβ line, 0.01 Å for the HeI 5876 Å, Ca II 8542 Å, and NaI doublet lines, 0.08Å for the HeI 10830 Å line, and 0.05 Å for Paγ.
