An ACS H-alpha mosaic of NGC 3324 already exists (HST proposal 10475, PI Nathan Smith). This program will use WFPC2 to obtain two more filters for this field.

A linear mosaic of WFPC2 pointings, designed to match the existing ACS H-alpha mosaic as much as possible. In addition to the large mosaic shifts, there are small dithers for the rejection of cosmic rays and detector artifacts. The mosaic strategy combined with the quantized WFPC2 exposure times somewhat dictates the 400s and 500s exposure times. Happy 10th Anniversary to the Hubble Heritage Team. This will be our "last hurrah" with the venerable WFPC2, which will be removed during Hubble Servicing Mission 4, after 15 outstanding years of service on orbit. 0 false 0.0 0.0 false false false false false SUPPORTED ISM DARK CLOUD HII REGION STAR FORMING REGION This object was generated by the targetselector and retrieved from the NED database.
