A data.frame containing the minimum and maximum range expected for index values generated using get_indices().
Used to flag indices that warrant further examination to ensure accuracy.
Format
A data.frame with 62 rows and 5 columns:
index_method: The index method used to calculate the index
index: Name of the index metric calculated
low_val: Minimum value expected based on literature sources
high_val: Maximum value expected based on literature sources
source: Sources used to determine minimum and maximum values
