This page describes ALMASim’s ALMA metadata workflows.
Location
Metadata code lives in:
Capabilities
ALMASim can:
query ALMA metadata through TAP
normalize TAP columns into stable application fields
infer array type from antenna metadata
export metadata rows to CSV
feed metadata rows directly into simulation workflows
Metadata-Driven Simulation
Metadata rows are used to derive:
target coordinates
ALMA band and frequency support
PWV
integration time
field of view
angular and velocity resolution
continuum sensitivity
line sensitivity
antenna arrays
observation configuration splits
The simulation page uses metadata rows as the main source of truth and only uses manual form fields as overrides.
Query Interfaces
ALMASim supports metadata usage through:
Python services
backend API
frontend metadata page
CLI example scripts
notebooks
