Why Polaris isn't listed?

[Rumata]

CelNav57, 

I tried to use Pub.249 for Hc for Polaris, LHA =227. It isn't listed.  Yes, I can use NA-93 and find SHA but how can I use Pub.249?  In 229 no questions, just LHA of the object and Decl.  But Pub.249 just lists selected stars. Meaning I need to use 229 in this case. Am I missing something?  Thanks.

Greetings,

I found kind of answer to my question. I found the formula for Hc .  Still don't understand why it isn't listed in Pub.249. But calc is not difficult. So be it.
