Strange values in Bitcon Electrum wallet file (change and receiving)

Question

I am performing a forensics analysis of a Bitcoin Electrum wallet. When I open the file manually, there are values like this (changed it a bit):

"accounts": {
    "0": {
        "change": [
            "039de61d6f91d6e419641ef61d5df1f65d1fddddfd6fd1e84fe6fd1f1d6dfb5958", 
            "02f2ffe6f8d6df5df6e84f684fdf5416d1f6e8ef4964ffd3f3dfdfefe46f1d1f56", 
            "037bf6d541df651df3513df1d3f1d35fe6f4e6f4d5fd65fe65f1d3f1d3f1dea996", 
            "0266e5f1d651df6d1f6df1dfff6df51d65f1d65f1d6f46ef4ef65f1eff65e1fd3f", 
            "02651e65e1e1d1d6e1e5e1e6e6e6e6e65e1e1d31fd3f1d35df13d1f3d5fe216e71", 
            "036ef6d1f351d3f131df3df13d51f1d351fd35135151111131df35d1f3df13dcc2"
        ], 
        "receiving": [
            "03f6d41f6d51d31df3fe13f1d3521fd35fe5131ff1f11f133fd31fd35d1fd3f639", 
            "026e61fd6df1fd6fd6f16d1fdc6c1d6f1d6f1e61f8d4d6c1d65f6df1df1d3f5e14", 
            "03ef1dsdgsdgsg6f1d6d1c6d51fd651fed1c63d13fd13f1d32f1d3f31db5e8286a", 

...

I thought that these should be just addresses, but obviously they are not. It gets even stranger when I import the file into Electrum - it then automatically changes these values to addresses (in the file too). I don't think, that it's something like a private key - it's 66 chars long. Even if - when imported, Electrum still asks me for it. What does this all mean and how do I get information about transactions/addresses/amounts?

The fields you are seeing are raw ECDSA public keys.
