Follow-up budget: A real follow-up might proceed as follows: Use 1-m class telescopes near max for all bands Switch to 2.5-m class telescopes a) for U-band two weeks after max b) for all UBV during periods when moon is unavoidable -5 < T-Tmax < 60, no Moon, 20 lc points 1-m 2.5-m U B V U B V Bmax = 19 38 4 1 6 1 1 min/point Bmax = 20 218 20 5 35 3 1 min/point Bmax = 21 1321 113 29 211 18 5 min/point Bmax = 22 8188 685 170 1310 110 27 min/point 1-m 2.5-m U B V U B V Bmax = 19 12.7 1.3 0.3 2.0 0.3 0.3 hrs/lc Bmax = 20 72.7 6.7 1.7 11.7 1.0 0.3 hrs/lc Bmax = 21 440.0 37.7 9.7 70.3 6.0 1.7 hrs/lc Bmax = 22 272.9 228.3 56.7 436.7 36.7 9.0 hrs/lc Note that most of the time comes at late epochs. LCO Swope + Tek% was zeropoints were used. Tek5 has best blue response, so these are minimum values.
