Supplementary Notes 

A variable star search of Pal 11 was carried out by Kinman & Rosino 
(1962) but no variables were detected.

A VI color-magnitude diagram published by Lewis et al. (2006) shows
noticeable, but depleted red giant and subgiant branches. It has a red
horizontal branch, characteristic of a metal rich cluster cluster. 
In fact, they found that the CMD was virtually identical to that of the
metal rich cluster NGC 5927.
There are also a few blue stragglers but the data were not extensive 
enough to carry out a search for variables.
