Handling candidate alerts and metadata for DSA-110. Uses Caltech Data, Transient Name Server, and VOEvent protocols to publish/share/distribute discoveries.

• voevent-parse
• caltechdata_api
• datacite
• requests

<git clone dsa110-event and cd into directory>
pip install -r requirements.txt
python setup.py install

Start with T2 json with initial (search beam) localization:

• create_voevent -- creates standard VOEvent file.
• send_voevent (in development) -- sends VOEvent to a broker or partner.

Start with T3 json with rough, real-time calibration and localization:

• create_voevent -- creates standard VOEvent file.
• send_voevent (in development) -- sends VOEvent to a broker or partner.
• optionally:
  • Use T2 data as input to publication of event (ctd_send, tns_create, and archive_update, as below).
  • Important to save Caltech Data metadata file, in case updates are required. Keep it in the candidates data area.

Start with T3 json with full calibration and localization:

• ctd_send -- get DOI and upload discovery plot. Creates metadata needed for updates and making archive update.
• tns_create -- use T3 json to get official name and broadcast to public (with prop period, if needed).
• archive_update -- adds line to DSA-110 event archive with link to data DOI, nickname, and official name.

Or if sub-arcmin localization already published, then modify the Caltech Data metadata and pass to ctd_update and archive_update.
