Phase 2

Phase 2 Generation for Cycle 12

All Projects approved for observations with ALMA need to go through the Phase 2 generation.  Since Cycle 8 2021, PIs are not requested to submit their validated Science Goals (SGs). The Scheduling Blocks (SBs) corresponding to all approved SGs will be generated by the Observatory in batch mode. Shortly after receiving the notification letters, PIs of approved projects are contacted by ALMA via a Helpdesk ticket. The Project Helpdesk ticket is assigned to a Contact Scientist who will be happy to assist with any queries that may arise. Any necessary communication between the PI and ALMA concerning the approved project should proceed by replying to this Helpdesk ticket. The only exception is for major change requests, which require official change request tickets that have to be submitted by the PIs before the first SB execution. If your project requires Total Power observations and you want to override the observatory-provided reference position, you may also do so on the project ticket before the first SB execution.

Users may also reference the Phase 2 Quickstart Guide, the ALMA Proposer's Guide and the ALMA Technical Handbook for the present Cycle.

The ALMA Observing Tool (OT) is a Java application used by PIs for the preparation and submission of ALMA Phase 1 (observing proposal) and by ALMA staff for Phase 2 (telescope runfiles for accepted proposals) materials. The OT should run on all common operating systems and depends on a version of Java being available. The Cycle 12 can only be installed manually with a tarball distribution, as an installer is not available. 

The tarball version and the instructions for its manual installation can be found clicking on the button:

NOTE: For those who require the Cycle 11 version of the OT, it can be found here.
