ska_oso_pdm.entities.common.sb_definition
The sb_definition module models SB data model entities concerned with the high-level composition of a Scheduling Block. An SB defines everything needed to schedule and perform an observation, for instance:
Target telescope
Dish allocations to sub-arrays (for SKA MID);
Dish configurations (receiver bands, etc., for SKA MID);
MCCS resource allocations to sub-arrays (for SKA LOW);
Sub-array Beam configurations (channels, antenna weights etc., for SKA LOW);
Target Beam configuration, defining the required Target for subarray beam configuration (for SKA LOW);
Targets and field positions, describing which points to observe on the sky;
CSP (Central Signal Processing) correlator configurations to be used;
SDHP configuration, defining the required pipeline workflows for the observation;
Scan information, which describes which CSP/SDHP/dish/target configurations to be used for each scan;
Scan sequence describing the sequence of scans constituting the observation.
as well as:
SB metadata (author, creation date and version number, as well as edit history);
SB script execution requirements;
The contents of the module are presented in the diagram below.
