Note:
The presence of numerous P-Cyg profile (Na lines for example) and the presence of prominent
Fe II
series emissions ("Fe II" type nova - see classification of Williams
(1992), AJ, 104, 725). For the date and this resolutio the H-alpha emission peak is 2.94 times the intensity of the
nearby continuum at 6630 A.

Note:
This spectrum cover an extended infrared domain. The
H-alpha emission peak is 7.70 times the intensity of the
nearby continuum at 6630 A for this spectral resolution. The intensity of H-alpha and H-beta lines decrease.
The Ca II triplet is prominent in the infrared (8498.1, 8542.1 and
8662.2 A). The mean continuum is very "flat" after removal of the
instrumental response.
