Nice write-up about this on your blog, Emily. However, I think that the release image shows both the actual data from VIRTIS, as well as a simulated view of temperatures based on altimetry data from Magellan, not VIRTIS data corrected for altitude. Yes, the Magellan map is modelled temperature based on topography and some assumed lapse rate. The key here is to look for differences between measured and modelled temps, which might reveal hot spots - active volcanism. And Emily - your map of the Venus hemisphere is - alas - wrong! You are looking at Ovda Regio, not Phoebe. You're about 180 degrees off. Mixed up east and west longitudes? Ooopss.... no wonder I was having a hard time finding the spots on the ESA release on that globe. I apologize for the mistakes. Not my best work at all. Thanks for the corrections, guys. --Emily -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.
