Observing a minor planet with RTS2

As of May 4 2018:

To observe a minor planet, make a new target with rts2-newtarget, and give it the minor planet ephemeris in MPEC format, like this:

00021 7.35 0.11 K183N 240.62102 249.91805 80.87133 3.06377 0.1640975 0.25933042 2.4353819 0 MPO445254

Ephemerides for minor planets can be found at (https://minorplanetcenter.net), for example (https://minorplanetcenter.net/iau/Ephemerides/Bright/2018/index.html) for bright asteroids. The full listing there looks like

00021 7.35 0.11 K183N 240.62102 249.91805 80.87133 3.06377 0.1640975 0.25933042 2.4353819 0 MPO445254 4448 71 1866-2018 0.39 M-v 38h MPCLINUX 0000 (21) Lutetia 20180425

and we think that you need the fields shown in the first example, but have not yet tested what happens if you paste the whole line in.

Currently it appears that rts2 is acquiring the object in RA,Dec at beginning of each exposure. This means that it may be pointing correctly at the object in each exposure, but the individual exposures themselves will be trailed - it's not applying bias rates to the tracking. This is under test.
