FGS Phase I

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