Proposing for WFC3

When writing and submitting an WFC3 Proposal, proposers should consult all relevant technical documentation about the capabilities and sensitivities of WFC3. Two important documents to consult are the WFC3 Instrument Handbook, and the WFC3 Data Handbook. Proposers should also discuss the requirements of their observing programs with appropriate STScI experts. Contacts are provided via the STScI HelpDesk.
