Q2.3 119.5 is #glitch21
Q2.3 114.5 is #fp16 glitch
Before anyone shouts "Transit!", let me first say it's probably a #glitch21
#glitch21 bad data
Known Bad Data locations in Q2.3: 21.14-21.17, 24.66, 24.70-24.72, 25.02, 26.66, 27.03
Unfortunately, those are both known data errors. The day 21 dip (#glitch21) shows up in a lot of the quarter 2.3 data. And, the day 16.5 dip is part of an much longer pattern that shows up in all of the quarter 2 data taken by mod.out 2.3 (#fp16).
Hm, yes, it looks not bad. I actually did not look closer at the data, but was more referring to his mentioning of "very common occurrence". But the #glitch21 is usually only a few pixels long (probably only the pixels at 119.44-119.47 in this case).
#fp16 as well as #glitch21
Known bad data in Q2.3 : at 21.14-21.17 and 25.02 (among others), especially the day 21 (#glitch21) feature really can be confused with a transit.
