These files are snapshots of plots from explorer that represent solutions to 
a system of reaction-diffusion equations with Dynamics specified by Roger 
Nisbet for plankton interactions.  The parameters that are varied are carrying capacity (k) and predator death rate (m).  The files are named as follows:

   n = Nisbet
   The first decimal number is the value of m  
   The second decimal number is the value of k

   If there is a b in the name the problem setup was,

                    xmax=1000
                    npts=5001 
                    tmax =900
                    dt=.01

   otherwise the setup was,

                    xmax=250
                    npts=2501 
                    tmax =300
                    dt=.01
   
   if there is a c in the name then,


                    xmax=2000
                    npts=10001 
                    tmax =2000
                    dt=.01


For example

n_.02_.6b.rgb: Nisbet, m=.02, k=.6,xmax=1000, npts=5001, tmax =900, dt=.01
