Comments:


1. MinII V = 13.2.

2. MinII V = 14.8.

3. MinII V = 13.5, D = 0.12P. P = 0.9935d (Paschke 2007) is erroneous.

4. MinII V = 11.7.

5. MinII V = 13.8. D = 0.08P:.

7. VB. The ASAS-3 range is for the combined brightness of the variable star and its neighbor. Coordinates of the western star of the pair are given. It is not clear if the western star or the eastern star (14 23 32.56 -59 50 25.3) actually varies. MinII V = 13.2, D = 0.08P.

8. MinII V = 14.5.

9. MinII V = 12.50, D = 0.17P.

10. MinII V = 14.0:, D = 0.12P.

11. MinII V = 13.5:.

12. M - m = 0.18P. The RafV catalog also gives the variability type RRAB.

13. MinII V = 13.9:, D = 0.07P. P = 0.3905d (Paschke 2007) is erroneous.

15. J - Ks = 0.29 (2MASS).

Remarks:
In 2005 - 2009, Radek Dreveny, Anton Paschke, and Friedhelm Hund (with participation of Thomas Sauer) discovered about 140 new variable stars and presented their results as a web catalog (the RafV catalog, http://var.astro.cz/newrafv.php?land=en). Some of the stars listed in the catalog have been studied in sufficient detail, others remain virtually unstudied. We checked all the poorly studied variables of the catalog for possibilities to investigate them using the publicly available electronic archives of CCD observations of the ASAS-3 project (Pojmanski 2002). Here we present the results of our study of 16 variables. None of them are contained in the catalog of variable stars discovered in the ASAS-3 project, the International Variable Star Index (VSX), or the GCVS.

The tabulated coordinates of the variable stars are from the 2MASS Point Source Catalog.
