5. Create a new tpf list pointing to these unzipped files

This is done with a quick command from the terminal. 
ls tpfs/*.fits > tpflist_downloaded.out

6. For a given quarter and channel, stitch together TPFs for each of the cadences

Because of memory issues experienced by both myself and R. McClure, we were stitching the cadences one-by-one using a python script. This is in contrast to the bulk cadence stitching performed in the example here. We can ignore that now that we have done steps 4 & 5. 
Simply perform the following to stitch your tpfs:
k2mosaic mosaic tpflist_downloaded.out
