====== Trivia ====== Etymology of OpihiExarata ========================= The IRTF Opihi telescope is named after the `opihi`_, a limpet which lives on rocky shores by sticking to the rocks. In a similar vein, the Opihi telescope sticks hard onto the side of the main IRTF telescope. One of the three opihi species endemic to the Hawaii islands is the `Hawaiian blackfoot opihi`_. The Opihi telescope is similar to this species and for this reason, this software is named after it. (The similarities: the opihi species and the telescope are both black; the Opihi telescope is rather small compared to the IRTF, the blackfoot is a small opihi; and the blackfoot opihi is a high delicacy, similar to this software, it has a rather small audience.) The binomial taxonomical name of the Hawaiian blackfoot opihi is Cellana exarata. The genus Cellana describes the group of limpets including the opihi, but *exarata* is the identifying part for the Hawaiian blackfoot, thus the name of this software, we decided, is the hybrid: OpihiExarata. A backronym for it, descriptive of its function: OPIHI Ephemeris with eXtra Atmospheric Response and Asteroid Trajectory Analysis. .. _opihi: https://www.waikikiaquarium.org/experience/animal-guide/invertebrates/molluscs/opihi/ .. _Hawaiian blackfoot opihi: https://en.wikipedia.org/wiki/Cellana_exarata
