PGPLOT windows for Burnf code

Explanation of the main features of the on-screen plots


WINDOW 1 Plot of log(Y_i) (number fraction), on a Z vs. N plot.
Abundances are color and size coded as listed on the key on the upper left. For current plot, protons (large magenta dot) and He4 (big red dot) are most abundant, followed by C12 and O16 (yellow dots).
The dark grey dots represent the network specified by NUC.NET, dark grey diagonal line is Z=N line, dark grey horizontal lines mark some important elements.
At the bottom are the current time in sec, current temperature in K, current density in grams/cc.




WINDOW 3 Shows the reactions that are producing above THRESH*EMAX ergs/g/s (within some fraction of the energy of the reaction with the largest energy - e.g. if THRESH=1.00E+00, only the maximum energy flow will be plotted). This is similar to the FLMIN parameter in NUC.IN. The value of thresh can be set in NUC.IN .
The colored solid squares represent a P, N or He4 in the input or output channel of a reaction.
The arrows and empty colored boxes represent the other nuclei in the input and output channels. Their color is coded according to what deck the reaction is in. BURNF arranges reactions into decks depending on type
    deck 1: electron captures and Beta decays i --> j
    deck 2 and 4: dissociations, i ---> j + k and captures, i + j ---> k
    deck 3: dissociations, i ---> j + k + l
    deck 5: exchange, i + j ---> k + l
    deck 6: exchange, i + j ---> k + l + m
    deck 7: exchange, i + j ---> k + l + m + n
    deck 8: includes triple-alpha reaction
There will also be window #2 which contains a written list of the reactions plotted in window #3, color coded by deck. It will list the deck number, reaction number, the reaction itself, and its energy.
The dark grey dots represent the network specified by NUC.NET, dark grey diagonal line is Z=N line, dark grey horizontal lines mark some important elements.
At the bottom are the reaction number (assigned in Burnf for a specific NUC.NET) and energy of the most energetic flow, current time in sec, current temperature in K, current density in grams/cc.
In the example shown here, there are a number of magenta (deck 4) reactions, which are proton captures (yellow solid box)
