Epics- VLA Calibration Improvement: Improvements to the flagging heuristics for system and RFI Issues.
- RFI heuristics for VLA PI pipeline will be modified - moving toward VLASS or VLASS-derived

- Heuristic changes for bad deformatter identification
- proper multi-band support

- allow different bandpass calibrators per band
- API plot should appear in weblog
- gaintable flagging of final gaintables based on statistics (do within final cals?)

- per-baseband delay capability should be implemented
- ability to use spw-mapping per baseband for final gain calibration in low S/N regime (mixed spw setups)
- pipeline should use fluxboot2 results to determine if gain calibration on individual spws will have too low S/N
- switched power weights (CASR-476)
- mstransform hanning smooth pass through (CASR-357)
- SPW intents and processing options need to be passed from RCT/OPT to pipeline
- SDM option
- PPR option
- Intents : Spectral Line or Continuum
- Processing Options: Hanning smooth, RFI Flagging, Statwt

- batch request capability
- upload formatted catalog, obtain cutouts against selected image collections (e.g., ALMA, VLASS)
- Metadata Improvement: Improved meta-data for products in the archive.
- Migrate to a refreshed archive-new interface

- VLA/SRDP QA
- Weblog from Calibrations linked and viewable through archive
- VLA
- ALMA Calibration
- ALMA Imaging (If separate from Calibration run)
- ALMA SRDP Imaging
- Proprietary state properly reported
- VLA Receiver Band Metadata correction
- Fix older EVLA data (listed as subband...)
- Angular resolution
- Displayed per MOUS for ALMA
- Tabulated approximately per VLA band/configuration
- Conform to standard results table from System Requirements document
- CARTA- Archive Integration: Integration of the CARTA viewer with the Archive.
- Support starting CARTA backend (require to be logged-in) and user views through new web browser tab
- User should be able to select an image product and open it in CARTA
- User should see a progress bar so they know what is happening
- important for large cubes that are not available within seconds
- Ability to open second image from archive within CARTA and overlay
- Regions support is required
- region information should be available to archive interface for cutout or search functionality
- Ability to upload their own image
- Overlay catalogs (available in archive or external catalog available in CARTA)
- those in archive (e.g., NVSS, VLASS, etc)
- external catalogs available in CARTA (e.g., 2MASS, IRAS, GAIA)
- Upload user's catalog
- Catalog Support: Support for searchable scientific catalogs in the Archive
- Catalogs should be searchable from a subset of search filters
- Return results able to be used as query for project/observation/image searches
- Ability to hide columns
- Interface for projects to upload catalogs for ingestion
- Image Ingestion: If not already complete the ingestion and service of VLASS and ALMA images.
- ALMA
- ALMA cubes and continuum images associated with each MOUS need to be ingested
- ALMA image products must be displayed to users and downloadable
- Thumbnails should be present for ALMA image products
- Viewable in a CARTA session
- VLASS
- VLASS QL images from the entire first epoch must be ingested
- VLASS images must be displayed and downloadable
- VLASS images require thumbnails and high-resolution png images
- Viewable in CARTA session
