#  "Date" is the date of observation.
#
#  "01" through "17" are identifiers for the 17 vervets.
#
#  "A" through "F" are used to identify sleeping groups.  In other
#  words, for a particular date, all the vervets with the letter "A"
#  slept in one group, all those with the letter "B" slept in another
#  group and so on.  The value "-" indicates that the vervet was
#  not observed.
