| 2 | November 28 2002 | ISAN-NIVS 6.65 m | 1904–2327 |
| 3 | No. 514a Track no. 1 | NIST-NIVS 10m | 2333–2570 |
| 4 | No. 522a, b Track no. 5 | NIST-NIVS 10m | 2651–3213 |
Notes. (a)No. is the serial plate number according to the NIST archive classification. (b)ISAN – The Insititute of Spectroscopy of the Russian Academy of Sciences, Troitsk, Russia; NIST – National Institute of Science and Technology, Gaithersburg, USA; NIVS – normal incidence spectrograph. (c)Indication of which plates the classified lines of Table 7 belong to. In the present work, spectrum no. 1 was used to check possible blends by lines of the second diffraction orders.
