Calculation for angular distances

Hi...

I am working on angular distances between the objects...

I need solution for calculating the angular distances between group of objects... keeping one object as centric.

The example I have attached in excel sheet..

Kindly go through the sheet & solve the problem.

Thank You

In cell B16 I went with:

=VLOOKUP(MID(A16,FIND("-",A16)+1,255),$A$4:$B$13,2,FALSE)-VLOOKUP(LEFT(A16,FIND("-",A16)-1),$A$4:$B$13,2,FALSE)

And copied it down - seems to return the answers you're expecting.
