Variables
Light curves of some new-found variables. My data (gathered with DSLR) were transformed to Johnson V (Johnson B) system using an approach described in The AAVSO DSLR Observing Manual (standard transformation) or the "VSF" (synthetic V-filter) approach [R. Pieri] in some cases.
PMAK V1
Type: EW; Period= 0.40280 d
Range: 13.10 - 13.38 V
Note: initial epoch differs from those specified in the VSX by half of the period (it is hard to distinguish between the primary and the secondary minimum)
PMAK V3
PMAK V4
PMAK V5
Type: EA
Range: 13.15 - 13.6: V
Note 1: Magnitudes contaminated by 2MASS J21301793+3510301 (V= 14.5; sep. 5”), range has been corrected.
Note 2: Transformation from DSLR TG to Johnson V was done using VSF approach [R. Pieri]
Note 3: Period differs slightly from that specified in the VSX, it was recalculated.
