Scheduling in Targeted Transient Surveys and a New Telescope for CHASE

Table 1

For a desired detection age (𝜏_age) we show a possible choice of cadence in days (Δ𝑡), the maximum sample size consistent with this cadence, and the approximate detection rate if the suggested cadence and maximum sample sizes were used. 𝑡₀ corresponds to the time for the transient events to become visible since its occurrence; 𝑁_exp is the number of observations per night, and 𝑅 is the rate of events expected in each field. We assume that in all cases the time that a transient remains visible, 𝜏, is bigger than the cadence chosen. For the opposite case, Δ𝑡 can be replaced by 𝜏 in the last two columns below.
