I just finished module 11. I had a few comments. First, it is not clear which data in the measurements after applying the aperature tool are the brightness. I assumed it was the "source-sky". Second, what do the x and y values mean? Also, it is not clear if we are supposed to use the default values for the aperture photometry tool OR fill in with what is in the instructions for the module. The defaults I got were very different from the instructions...but I used the ones in the module anyway. Also, when creating the graph of blue and red values...which values do we use? I used the source-sky for mine. However, the data in my worksheet is not in order from hottest to coolest...but it is noted on the screenshot I sent you.
