The Bandpass of the MEarth Observatory

I recently found myself wanting to know the (approximate) bandpass of the MEarth observatory. A plot of the bandpass is published in Nutzman & Charbonneau (2008), but I wasn’t able to find any tabulated data. Fortunately, the MEarth team works down the hallway from me, so I could find out if there were any better options. The short story is, not really. Jonathan Irwin kindly sent me some of the underlying data, which I used to compute a bandpass. I wrote up my method and results in an IPython notebook, which is shown statically below.
