** Calculation of Boundaries **
Enter planetary radius.

Table of planetary radius and stellar flux boundaries can be downloaded from here.

(If you want to calculate the boundaries, download this fortran code) . Table of Coefficients can also be downloaded.

After entering the values in each box, just click inside each box to obtain the results.

R_{p} (units of R_Earth) Allowed values are: 0.5, 1.0, 1.75, 3.5, 6, 14.3 RE.
