LMP2021: Trouble understanding the Noise Analysis in TINA-TI

Part Number: LMP2021
Other Parts Discussed in Thread: TINA-TI,

I have searched for documentation that explains the Noise Analysis capabilities in TINA-TI (http://skory.z-net.hu/alkatresz/Tina_TexasInstruments_2009.pdf for instance) and have found no explicit mention of Input and Output Noise diagrams are referenced. If I place a voltage meter with an IO State of "output" on the output of an op amp circuit, will the Noise Analysis know to use that as my reference point? Similarly, can I expect a voltage meter set as "input" IO state to be used as the reference for the Input Noise diagram? 

What are the components that go into Total Noise? Is it a summation of noise for each modeled component in the schematic? 

Please pardon my ignorance and need for explicit definitions! Thanks in advance for your help,

-Adrian
