Newby: add topic to payload x 2

Hi
How do I add a topic to each of these two functions:

var msg1 = { payload:msg.payload};
var msg2 = { payload:msg.humidity};
return [msg1, msg2];

At this moment it returns two payloads

payload: 15
_msgid: "9c1a815f.88451"

payload: 60
_msgid: "9c1a815f.88451"

And I want it to return

payload: 15
_msgid: "9c1a815f.88451"
topic: "Temp"

payload: 60
_msgid: "9c1a815f.88451"
topic: "Humid"

Thanks for any help

Mathias

var msg1 = { topic: "Temp", payload:msg.payload}; 
var msg2 = { topic: "Humid", payload:msg.humidity};

Perfect. Thanks.
