The LSST EFD Client¶

The LSST EFD Client helps you access the LSST Engineering Facility Database (EFD), which is backed by InfluxDB. The client, EfdClient handles authentication and provides convenience methods for accessing data in ready-to-use formats:

get_topics: Get the topics in the EFD.
get_fields: Get the fields in a particular topic.
build_time_range_query: Build an InfluxQL query for a topic and time range.
select_time_series:: Get a DataFrame containing results of a time range query.
select_packed_time_series:: Get a DataFrame with high cadence telemetry expanded into a single DataFrame.
select_top_n: Get a DataFrame with the results of just the most recent rows.

Follow the Getting started guide to start accessing EFD data. Also, check out the demo notebooks for examples.
