In Cycle 0, full polarisation measurements are not offered. The OT will give you the choice of selecting Single-X or Dual (default). The default 'Dual' option will be the best choice for the vast majority of projects, as in single polarisation half the source flux is discarded. However, you may want to select the Single-X option if your project requires the very highest spectral resolution achievable (although you will sacrifice sensitivity and require a longer observing time).
Which of the two polarisation options offered in Cycle 0 (Single-X or Dual) is appropriate for my project? - Knowledgebase / Early Science - Cycle 0 - ALMA Science
