The abundances in the file s25a28c_expl.xml created here are for a time 25,000 seconds after core bounce. This is not long enough after the explosion for all of the short-lived species of interest to have decayed to their daughters (e.g., 18F). We will instead look at the abundances 106 seconds post core bounce.
To do this, we use the nuclear_decay NucNet Project. Follow the instructions at http://sourceforge.net/p/nucnet-projects/wiki/nuclear_decay/ to install and compile the relevant codes. Once the project is properly installed and compiled, change into the projects/nuclear_decay/ directory and type
(Typical execution time for an x86_64 type processor: 4-5 minutes.) This creates an XML file decayed.xml in the local directory in which all species with decay lifetime less than 10,000 seconds have been decayed to their daughters.
We now decay this file from 35,000 = 25,000 + 10,000 seconds to 106 seconds; thus, the decay interval is 106 - 35,000 = 965,000 seconds. Type
(Typical execution time for an x86_64 type processor: 5 minutes.) The output XML file s15a28c_expl_decayed.xml in the directory ../nucnet-tools-code/data_pub/s15a28a28/ contains the abundances from the post-supernova calculations at 106 seconds post core bounce.
Note that we could have decayed the abundances in the file s15a28c_expl.xml directly with the decay_abundances code. By carrying out the intermediate step, the decay_abundances calculation does not have to decay species with lifetimes less than 10,000 seconds. This greatly speeds up that calculation.
