Abstract Hubble Heritage proposes to observe NGC 3370 in conjunction with GO program 9351 (PI Adam Riess) to use the combined data to produce a three color image. ------------------------------------------------------------------------------------ Observations Description ------------------------ There are two visits, each 2 orbits, observing NGC 3370 with the same pattern and visits structure as 9351. Observations are made in the B-band (filter F435W) to combine with 9351's observations in V and I. The four orbits of this proposal should reasonably approximate the S/N achieved in 9351 V and I.
