s] is the areocentric longitude of the Sun as seen from Mars expressed in degrees.
We shall determine a suitable empirical mathematical law for interpolation of the points of the R-Ls graphic, so that for every areocentric longitude Ls we can derive a value for the cap's angular radius.
If dLs is a short arc of areocentric longitude and dR is a small decrease in the radius of the cap during this interval, the ratio V= dR/dLs, or first derivative of the function R(Ls), is the rapidity of the motion of the cap edge toward the pole while Mars proceeds along its orbit.
Date limits of May 8-August 4 yield areocentric longitudes (Ls) 186-240[degrees].
3), at areocentric longitude (Ls) 177[degrees], just before the start of southern martian spring.
