science.astro-colibri.alert.vo2

Event or source type used by Astro-COLIBRI. Includes transient classes, catalogue source classes, and tilepy observation tiles. Known values retain the spelling used by the filters and listeners; additional values are allowed.

• maxLength: 128
• knownValues: burst | frb | grb | grb_optical | gw | gw_optical | neutrino | nuem | ot | ot_other | ot_sn | star

Unique event identifier assigned by Astro-COLIBRI. It identifies the same event across revisions and payload formats.

• maxLength: 128

Broker, classifier, or service that submitted the event. Known values come from the general filter, plus GCN and TNS as emitted by the listeners. An empty string means unspecified; additional brokers are allowed.

Timestamp when this AT Protocol alert record was created, including a timezone (prefer UTC with a Z suffix). This is distinct from the event detection time in data.

Full VOEvent 2.0 document, exactly as published on the astrocolibri.important.VOEvent Kafka topic, converted to JSON with xmltodict.parse(xml, attr_prefix="") (the format /voevent?json=1 returns; see https://astro-colibri.science/apidoc#voevent_json). Retain the root key (for example voe:VOEvent), namespace attributes, and Who, What, WhereWhen, How, Why, and Citations sections when present. Every XML attribute and text value is a string, so the document contains no floating-point numbers; repeated elements may be arrays. The payload is intentionally open to preserve instrument-specific content.

Whether this alert qualifies for the Astro-COLIBRI important stream. This is separate from the VOEvent Why.importance value. See https://astro-colibri.science/brokerdoc#important for the criteria.

Instrument or analysis that detected or localized the event, when known. Additional instruments are allowed.
