#  Suggested "light" defaults for Sn atom (to be pasted into control.in file)
#  Be sure to double-check any results obtained with these settings for post-processing,
#  e.g., with the "tight" defaults and larger basis sets.
#
#  2020/09/22 Added f function to light settings to improve bulk properties of In-I.
