Project description


Utility classes for working with the LSST EFD.

  • Free software: MIT license


  • The client EfdClient, has several useful functions.

    • get_topics: Return the topics in the EFD.

    • get_fields: Return the fields in a particular topic

    • build_time_range_query: Build an InfluxQL query for a topic and time range

    • select_time_series: Return a DataFrame containing results of a time range query

    • select_packed_time_series: Return a DataFrame with high cadence telemetry expanded into a single DataFrame.

    • select_top_n: Return a DataFrame with the results of just the most recent rows.

See example notebooks here.


Credentials for authenticating to available EFDs are held in a special file on disk. By default, this location is ~/.lsst/notebook_auth.yaml. The file must exist and must have 006 permissions set. The format of the file is a YAML dictionary of valid EFD names. Each EFD entry should contain the username, password, and host for the EFD. Currently, my file looks like this:

  username: <user>
  password: <passwd>
  host: ""
  username: <user>
  password: <passwd>
  host: ""
