Table 2
Analysis of the S/N between each of the two templates and three different subsets of the available observations.
| Airmass | N |  |
Observations | S/N (a) |
|---|---|---|---|---|
| All(b) | 3.7 ± 2.1 | |||
| ⩽1.2 | 8 | 2.8 | Template (c) | 3.4 ± 0.5 |
| S /N ⩾100 (d) | 3.3 ± 0.5 | |||
| All(b) | 4.4 ± 1.9 | |||
| ⩽1.5 | 13 | 3.6 | Template (c) | 4.1 ± 0.9 |
| S /N ⩾ 100 (d) | 3.9 ± 0.6 | |||
Notes. (a)The values and the associated uncertainty represent the median and standard deviation of the S/Ns; (b)Compares the two templates to all available observations from the two sets; (c)Comparison with only those that were used to construct the corresponding stellar template;(d)Comparison with all observations that have a S/N of higher than 100 in the 100th order.
