# Define the lists of observatories.  Latitude is in degrees, with
# north being positive.  Longitude is also in degrees, with east being
# positive.  timezone_integer is number of hours from UTC; timezone is
# a string that will be recognized as a valid timezone name by
# DateTime::TimeZone.   If you want to add something here and need to
# find the proper timezone name, you can run
#
#  perl -e 'use DateTime; \
#     $country = "US";  # or other two-letter country code. \
#     print join("\n", DateTime::TimeZone->names_in_country($country)); ' 
#
# to see a list of timezone names for the given country.  Or call
# DateTime::TimeZone->all_names in the same way to get every name.
