Comments:


3. The ASAS-3 range is for the combined brightness of the Mira and its neighbors.

5. The ASAS-3 range is for the combined brightness of the Mira and its neighbor. R = 15.3 on the USNO Archive image of 1992.2779.

7. The ASAS-3 range is for the combined brightness of the Mira and its neighbor. R = 14.3 on the USNO Archive image of 1982.2930. NSV 07496 = NSV 07491.

12. USNO-A2.0: B = 19.7, pg = 15.6 – <17.3 by Luyten (1935).

13. R = 15.0 on the USNO Archive image of 1991.5852.

16. R = 16.0 on the USNO Archive image of 1991.2786.

18. R = 15.8 on the USNO Archive image of 1992.2752.

19. R = 16.5 on the USNO Archive image of 1992.6366.

20. R = 16.0 on the USNO Archive image of 1991.5852.

23. R = 15.2 on the USNO Archive image of 1991.5852.

Remarks:
We recovered the variables NSV 07494, NSV 07506 and NSV 7684 suspected by Luyten (1933a); NSV 07464 suspected by Luyten (1933b); NSV 07487 and NSV 07496 suspected by Luyten (1934); NSV 07468, NSV 07485, NSV 07649, NSV 07678, NSV 07686, NSV 07709, NSV 07792, NSV 07818, NSV 07831, NSV 07834, NSV 07849 and NSV 07898 suspected by Luyten (1935); NSV 07436, NSV 07483, NSV 07511, NSV 07518, NSV 07659 and NSV 07759 suspected by Luyten (1936); NSV 07715 suspected by Luyten (1937). Finding charts, light elements and variability types for these variables have never been published. We could study the variables thanks to the publicly available electronic archives of CCD observations of the ASAS-3 project (Pojmanski 2002) and to images of the US Naval Observatory Image and Catalogue Archive.
