I wish to know, if the bellow sentence is grammatically correct and where I can find more information on forming such sentences
Can you share with me the coordinates of the measuring station, who's data you sent me last week?
Context: Last week a friend of mine sent me some data and asked me to analyse it. Now I wish to know the coordinates, but I'm not sure, if by using who in the sentence, I am referring to the measuring station in the correct manner (is it a he, a she, or an it).
