Relationship between the amount of all detected planets and the number of observations per star for the 78 sample stars (black dots, uncertainty (0.92N_P)^0.5), of the terrestrial planets (red squares, (0.62N_P)^0.5), the habitable planets (blue triangles, (0.95N_P)^0.5) and the false positives (black dashed line, (1.17N_P)^0.5). We indicate at the top the number of total observation times. With the 891 h total observation time and 34.3 observations per star on average of our survey (vertical black dashed line). We detect approximately 2.1 planets resembling the detection rate for evenly distributed 35 observations per star.
