NEEDLE-TRACK

Transient Recognition, Annotation, and Classification Kit

System Overview

NEEDLE-TRACK is a local system (with future migration potential to cloud or other machines) for managing transient data from Lasair (ZTF). It provides structured data storage, update tracking, search capabilities, and a publicly available package for easy deployment.

Core Components

1. Local System Management

   • Designed to run locally, with future migration capability to cloud or other machines.
   • Configuration options allow users to set up the system on various environments.

2. Database for Data Storage

   • Stores transient objects with changeable tags and associated comments for further annotation.
   • Maintains an Update List to track objects whose data has changed or that have new incoming updates.
   • Supports updates and tracking of object status changes.

3. Terminal Interface

   • Users interact with the system through a command-line interface (CLI).
   • Provides commands for ingestion, searching, commenting, and annotation.

4. Search Function

   • Query objects by unique ZTF ID.
   • Filter objects based on tags.
   • Search based on annotation status (astronote presence).

5. Public Package Distribution

   • The package, named needle_track, is hosted on GitHub for public access.
   • Includes installation instructions, dependencies, and usage guidelines.

Data Ingestion

1. Source: Data exported from Lasair broker (ZTF).
2. Format: JSON.
3. Update Mechanism:
   • Runs a script to fetch the latest data (default: past week, customizable).
   • Checks for overlapping entries:
     • Overlap Check: Compares incoming data with existing records.
       • If overlaps are detected, the system updates the existing record and logs it into the Update List.
       • New records are added directly to the database.
       • Objects that are not interested are moved to the Removed List.
   • Generates a report summarizing all updates and changes.

Data Storage

1. SQL Database Structure:

   • object table: list of all objects in the database.

2. Object Structure:

   • ZTF ID: Unique identifier from Lasair.
   • Object Properties: Data and metadata from Lasair.
   • followup: indicator if the object has been marked for followup.
   • snoozed: indicator if the object has been marked as snoozed.
   • astronote: indicator if the object has been marked as astronote.
   • Comments: User-added comments or notes for each object.
   • Link: URL reference to the Lasair entry for further details.

Tutorial

1. Initialize the database
   • needle-track -i
2. Ingest data
   • needle-track ingest --slsn <path_to_data> --tde <path_to_data>
3. Search for objects
   • needle-track search --objectId/-o <object_id>
   • needle-track search --followup/-f
   • needle-track search --snoozed/-s
   • needle-track search --astronote/-a
   • needle-track search --list/-l
4. Update objects
   • needle-track update --objectId/-o <object_id> --followup/-f
   • needle-track update --objectId/-o <object_id> --snoozed/-s
   • needle-track update --objectId/-o <object_id> --astronote/-a
5. Add comments
   • needle-track comment -o <object_id> -c "This is a comment"
