Adding WFPC2 parallels to ACS Observations: My science would really benefit from adding WFPC2 parallels to my ACS observations. Is it OK for me to add them? Reply: The information provided to Cycle 11 proposers was contradictory with regard to using WFPC2 for coordinated parallel observations when ACS is the prime instrument. In the interests of fairness, PIs may request to have WFPC2 coodinated parallels added to their program. This may only be done if the prime instrument is ACS, and the need for coordinated parallels must be fully justified to show that the parallels will provide useful science and to show that science from the parallels is directly related to the goals of the primary program. Please bear in mind that a default WFPC2 parallel program exists to obtain generic observations whenever possible. If you wish to add coordinated parallels to your ACS program, you must submit a Program Change Request by going to: http://www.stsci.edu/public/request.html
