      Nathan Myhrvold's “simple guide” to his 110-page NEOWISE asteroid criticisms is 5,400 words, not including refs http://bit.ly/1WklGWJ

      And a simple way to see how *wildly* wrong that guy is, just see the three verifiable measures - https://groups.yahoo.com/neo/groups/mpml/conversations/messages/32032 …

      NEOWISE is wildly wrong at times too. Would be amazing if it weren’t. It’s assuming spherical asteroids + fudge factors.

      Do you have an example of NEOWISE being wildly wrong? Anything like this guy saying 39x34km asteroid is actually 6.6km?

      Al the Elder mentioned asteroids with NEOWISE albedos of ~1.0. No one thinks they are really that bright.

      Specifically: any example of NEOWISE measurement of the size of a known size asteroid being wildly wrong? One example?

      1. Their own claim is error more than 10% half of the time,

      2. They calibrated fudge factors to known asteroid sizes, so they should be close, right? Would really like someone to explain.

      3. I would say an albedo of 1.0 would likely be “wildly wrong.” But can’t check independently.

      3. Example of asteroid size measurement being wildly wrong, please. Or please admit that you do not have such an example. /1

      If Dave Herald hadn’t posted, you wouldn’t have your example, either. I can’t report a story in reverse time.

          The occultation data IS interesting and worth following up on. But one data point doesn’t refute everything by itself.

          Nathan could be entirely wrong. But that’s not what people told me when I talked to them.
