A conversation with Dave revealed that I wasn't identifying tracklets correctly; he said that tot.itf is usually sorted by trksub, which means that naughty tracklets with repeat trksubs will be immediately after each other; the prior implementation of identify_tracklets would not have noticed that these were different tracklets, as it was only looking at the trksub of a line compared to the previous line. Now it also uses the time, for now imposing a limit of 24 hours between sequential observations of a tracklet.
I also demonstrate identify_tracklets in the Demonstrate_Sifter_PreCalc_and_SQLStorage_Functionality.ipynb notebook
