Consider adding a `KeplerTargetPixelFile.overlay_on_sky()` function
See original GitHub issueThis would not necessarily replace k2-pix
, because the latter provides a command-line interface etc… Instead, perhaps lightkurve
could provide the very basic functionality which k2-pix
imports.

I took a stab at this and I’m pretty happy with the aesthetics of the result. There are probably more clever ways to do some of this. I will note that these pixels don’t appear dead-on position when I compare to where the flux is distributed in the TPFs. Perhaps I’ve been a bit careless in the translation from RA,Dec to image location, or perhaps
get_coordinates()
has limited accuracy.result:![kic11090674_q4_keplerpixels](https://user-images.githubusercontent.com/6413923/44205771-d4d8ba00-a157-11e8-9096-950c1d38853e.png)
Let me know if you’d like me to proceed to implement an
KeplerTargetPixelFile.overlay_on_sky()
function like this.So, any suggestions on how or whether to implement this?
Has anyone quantified the accuracy of the
get_coordinates()
function? Is this affected by the same systematic offsets of up to 10 pixels described in https://github.com/KeplerGO/K2fov/issues/15? Unless we could provide ~sub-pixel accuracy withget_coordinates()
, I would be hesitant to provide this overlay functionality.
