Proposal Handling Tool Phase 2 (PHT-2)

PIs of accepted proposals will be required to follow Phase 2 of the proposal preparation process. The purpose of Phase 2 is to provide the detailed information required to schedule observations, in the form of observation requestions (ORs). Target information (including coordinates) together with the time awarded and target priority will be sent by ESA to the Science Operations Centre (SOC). The information sent will be based on the inputs given in PHT1 together with details of the awarded observing time and priority. This information will be used to partially pre-populate the observation requests (ORs), and will not be changeable by the PI. Access to the tool will require user credentials, which the SOC will provide to the proposal PI (edit access) and additional contact listed in the intial proposal (view access).
