Depending on time allocation policies, the project information in the ALMA Archive may be different from the Phase 1 proposal that the user originally sent to the observatory, e.g. a project may have been allocated less time than was applied for or a project may have been split into a number of smaller projects.
Therefore, if you have (an) approved observing project(s), the project information needs to be retrieved from the ALMA Archive and loaded into the OT. It may also be that the ALMA status (e.g. available configuations) has changed since the Phase 1 submission. In that case, the information in the OT about ALMA needs to be updated. For these reasons, it is always convenient and safer to start preparing your Phase 2 programme with up-to-date information concerning your observing project and the status of the ALMA Observatory.
