Comments:


2. 16.0 - 17.0 pg in Luyten (1934), B = 18.6 on the USNO Archive image of 1975.5086.

3. USNO-A2.0: R = 16.9. The ASAS-3 range is for the combined brightness of the Mira and its neighbor.

6. USNO-A2.0: R = 15.5. The ASAS-3 range is for the combined brightness of the Mira and its neighbor.

7. USNO-A2.0: R = 15.1.

13. USNO-A2.0: R = 17.1. The ASAS-3 range is for the combined brightness of the Mira and its neighbor.

14. B = 12.5 on the USNO Archive image of 1978.3258, B = 16.6 on the USNO Archive image of 1977.7755. The ASAS-3 range is for the combined brightness of the Mira and its neighbor. P = 279.8d and SR type of variability in the ASAS-3 variable-star catalog (Pojmanski 2002).

16. R = 16.0 on the DSS2 AAO of April 27, 1993. The ASAS-3 range is for the combined brightness of the Mira and its neighbor.

17. R = 16.0 on the ESO MAMA of March 31, 1994. The ASAS-3 range is for the combined brightness of the Mira and its neighbor.

18. R = 15.5 on the ESO MAMA of March 31, 1984.

19. 15.2 - <17.5 pg in Luyten (1935b), B = 19.1 on the USNO Archive image of 1976.3409.

23. 14.8 - <15.5 pg in Luyten (1935a), B = 17.8 on the USNO Archive image of 1975.1969.

24. The ASAS-3 range is for the combined brightness of the Mira and its neighbor. P = 296d and MISC type of variability in the ASAS-3 variable-star catalog (Pojmanski 2002).

25. This star was found, upon our request, by D. Williams on Harvard plates. The ASAS-3 range is for the combined brightness of the Mira and its neighbor. USNO-A2.0: R = 16.3.

Remarks:
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 (http://www.nofs.navy.mil/data/FchPix/). We recovered the variables NSV 07017 and NSV 07082 suspected by Luyten (1933a); NSV 07106 suspected by Luyten (1933b); NSV 06939, NSV 06975, NSV 06991, NSV 07011, NSV 07025, NSV 07035, NSV 07045, NSV 07047, NSV 07051 and NSV 07062 suspected by Luyten (1934); NSV 06907, NSV 06946, NSV 07022 and NSV 07083 suspected by Luyten (1935a); NSV 07106 suspected by Luyten (1935b). Finding charts for these suspected variables have never been published.
