 a wrong mirror was chosen, which was actually further away from the impact
 point than the mirror size, and therefore the photon was discarded later as
 "not hitting any mirror". Now we measure the distance on the paraboloid. The
 new code is:
+"not hitting any mirror" (about 20% loss for eco1000) Now we measure the
+distance on the paraboloid. The new code is:
   /*  calculate the mirror to be used */
 …
+    }
+  }
+Now the "distance" we calculate on the paraboloid is not a real distance,
+because sx,sy are measured along the cut between the paraboloid and planes
+containing the paraboloid axis and the x or y axis... but this should not
+matter much with such "flat" paraboloids. What cannot be done, as was before,
+is check the distance in the x,y,z space and then check whether the photon
+is inside the mirror in the sx,sy space, because then we lose photons for
+which a nearest mirror is chosen which in sx,sy is not close enough to
+contain the photon.
