Data frame containing one row per signal, with the following columns:

data_source: Data source name.
signal: Signal name.
min_time: First day for which this signal is available.
max_time: Most recent day for which this signal is available.
geo_type: Geographic level for which this signal is available, such as county, state, msa, or hrr. Most signals are available at multiple geographic levels and will hence be listed in multiple rows with their own metadata.
time_type: Temporal resolution at which this signal is reported. "day", for example, means the signal is reported daily.

min_value: Smallest value that has ever been reported.
max_value: Largest value that has ever been reported.
mean_value: Arithmetic mean of all reported values.
stdev_value: Sample standard deviation of all reported values.
max_issue: Most recent issue date for this signal.
min_lag: Smallest lag from observation to issue, in time_type units
max_lag: Largest lag from observation to issue, in time_type units
