data interpretation of TERMO MICROPHAZIR

Hi all.
I' m new user in NIR development, and I'm using the Method Generator Software for analyze the data  of Microphazir equipment. This give me the following results (picture), and I've some question for their interpretation 
 RMSE= RMSEP?
and the values the Slope and Offset belong to the coefficients of line equations?
For example the picture 
Y= 23.30146 + 0.7118447X + 0.1922865 (error) 
is this correct?

Thank in advance

Jorge
