To display Landolt data in Guide 7 (as a user-added dataset), take a
look here:

Other datasets of possible interest to those doing photometry:

http://www.projectpluto.com/extras.htm#Loneos_stds

In Guide 8, I put the Landolt data (and most of the smaller catalogs
on the "extras" page) onto the CDs. I didn't put the Henden dataset
in there, due to its size; and the LONEOS file gets updated regularly,
so you should probably download that from time to time anyway.
