+ Can you recover V_LSR=218.4 km/s and (U,V,W)=(11,12,7) km/s from M0III tracers from:
-     - An axisymmetric disc galaxy without extinction or error?
+     - A featureless axisymmetric disc galaxy without extinction or error?
-     - The same galaxy with dust extinction added?
+     - The same galaxy with dust extinction added? - Cut at V<20.2714 mag (~G=20 mag)
      - The same galaxy with dust extinction and Gaia like errors added?
-The ascii data is provided with the following format:
+^ Model ^ <latex>N</latex> ^ Data file ^
+| Full data | 5,999,999 | {{:data:1.dat.gz}} |
+| With extinction | 2,372,335 | {{:data:2.dat.gz}} |
+| With extinction & error | 2,372,335 | {{:data:3.dat.gz}} |
-===== Gaia errors code June 2015 =====
+All in the format: alpha (radians), delta (radians), parallax (arc second), mu-alpha (as/yr), mu-delta (as/yr), radial velocity (km/s), x (kpc), y (kpc), z (kpc), vx (km/s), vy (km/s), vz (km/s), mass (10^12 solar masses), V, V-I.
+(x,y,z,vx,vy,vz galactocentric, for checking purposes only!)
+The observer is assumed at (-8,0) kpc
+===== SNAPDRAGONS tutorial =====
+Has moved to: http://astrowiki.ph.surrey.ac.uk/dokuwiki/doku.php?id=snapdragons
+===== Gaia errors code September 2015 =====
 The code has been updated to compute the astrometric and photometric errors for a fraction of the operation data.
