[BioC] SKY/CGH data. How do I interpret it.

[S Peri]

Hi, 
 i am trying to make sense of CGH/SKY data. Can any
one who had worked with this kind of data help me to
understand the logic of this kind of representation of
the karyotype. How can I interpret the deletions and
additions. Apologies, if this question is out of place
here, but I did not find any other place where most
bioinformatics people visit.

Thank you in advance.
Peri. 

Karyotype:
