This diagram is a directed acyclic graph representing the ADMIT Task connections for the flow. Each arrow represents the connection from an ADMIT task output to the input of another ADMIT Task. The integer next to each arrow is the zero-based index of the ADMIT Task's output BDP. Note any output BDP may be used as the input for more than one ADMIT Task.


ADMIT Flow Diagram

Ingest_AT reads in a FITS image into ADMIT, creating a CASA image and extracting basic information. It is usually the first step in any ADMIT flow.
