Extended Data Table 2 Log of the optical and NIR spectroscopic observations of SN 2018evt

From: Newly formed dust within the circumstellar environment of SN Ia-CSM 2018evt

  1. The measured Hα luminosity and the equivalent width of the Ca II NIR triplet are also listed.
  2. a* marks the spectra that are already published in20,94.
  3. b Days since B-band maximum on MJD 58352 / 2018 August 22.
  4. c Uncertainty is derived and assumed that all spectra have 10% flux uncertainty. Note that the distance is not included. Only the Milky Way extinction is corrected with E(B-V)MW = 0.05 mag.
  5. Rv= 3.1.
