Products to be ingested
The VLA spectral line pipeline will make datacubes (RA, Dec, frequency axes) in addition to the continuum images. Each cube and continuum image should be a primary product, with its associated metadata, and take up one row in the results table.
Primary image products
Ancillary products
weblog.tgz - tarred and gzipped weblog
pipeline-<YYYMMDDTXXXXXX> - untarred weblog
placeholder.catalog.csv - empty file, will eventually contain source list
casa_pipescript.py - pipeline command script
casa_commands.log - list of equivalent CASA commands.
pipeline_manifest.xml - XML-formatted list of files
Product metadata
Product metadata should reflect the VO Obscore standard in terms of what we store, but fields can be named consistent with other image ingests:
- Position: ra,dec of image center
- Size: NAXIS1, NAXIS2 in pixels, from FITS file
- Resolution: sqrt(BMAJ*BMIN), beam axial ratio BMAJ/BMIN of the lowest frequency plane (resolution varies with frequency, most users will convolve to the lowest resolution)
- start time: DATE-OBS from FITS file
- end time: DATE-END from FITS file
- minimum frequency
- maximum frequency
- spectral resolution (spectral channel width; CRDELT3 in the FITS header)
- project
- polarization types: I
