In the following figure, we look at the time distribution of our sources, to see if it fits into the scheduling constraints given by ALMA. In the following figure, the top left image shows the RA distribution of source numbers, the right panel shows the time, gotten by dividing the bins by the total number of sources, and multiplying with the total time. According to the knowledgebase article https://help.almascience.org/index.php?/Knowledgebase/Article/View/402 and confirmed by helpdesk ticket #12729,
When evaluating the scheduling feasibility, PIs should assume that a source would be observed over an hour angle range of ± 3 hours for declinations of δ < 32 deg. For sources with δ > 32 deg, PIs may assume sources would be observed while above an elevation of 20 deg.
When we redistribute the source within a ± 3 h interval (since all of our sources are at δ < 32 deg) we end up with the distribution in the bottom for the two configurations C43-4 (left) and C43-1 (right). According to the Figure 4 in the Cycle 6 Proposers guide (reproduced at the end of this page), our distribution of sources per LST interval is fully compatible with the times available for large programs in C43-4 and C43-1. This can be even improved by redistributing some sources manually. We conclude that our time request is compatible with the restrictions of scheduling for large programs.
