Status Stakeholders John Tobin  Outcome 1. pipeline completes, no fluxboot warning, plotsummary indicates that the specline spw and continuum spw are scaled to match in amp --> qaPass, no note 2. pipeline completes, no fluxboot warning, plotsummary indicates that the specline spw has amp offset from continuum spw --> qaPass with note 3. pipeline completes, fluxboot warns spix >5 --> qaPass with note 4. pipeline fails (spix >100) --> qaFail, email with note Note: In fluxboot stage, the determined spectral index is unphysical due to the fitted centers of each spw being very close together compared to the overall bandwidth. Manual calibration with fitorder=0 in fluxscale task is recommended. Pipeline future development: Add a fractional bandwidth heuristic for cases where we would want to use a fitorder=0, and then make fitorder=0 work in the pipeline. Fluxscale can take a fitorder=0, so it's mainly a pipeline limitation. Due date When does this decision need to be made by? Owner Amy Kimball

Background

Project 22A-431 has setups with one continuum spw and one spectral line spw that have nearly the same center frequency. This can result in spix >5 which issues a warning, or even spix >100 which terminates the pipeline run.
