unable to determine the nest thermostat compatibility check

[shravee]

Dear Team, 

My existing honeywell thermostat has the following wiring connected. 

E, AUX, Y, O, G, A, C

G and A are not available to select in the nest compatibility checker and I could not determine it myself. I have attached the snapshot of the thermostat wiring. 

Can you please take a look and advise.
