| + | * in the desc_known list, include an entry "nu11" and "au12" for neutrino and antineutrino (no reason for the numbers - arbitrary name) | ||
| + | * increase ndesc by 2 (152-->154) to account for additional entries | ||
| + | * introduce new case in idesc switch statement (we called it case 153 and 154). set iec to 11 and 12 (matching the names above). Farther down, iwk1(n) is set to iec, where n is the number of the reaction. | ||

| + | * rpf1 is set to inverse partition-function stuff if inverse rate, 1 if forward rate (determined by whether a "v" is in the reaction rate database entry | ||
| + | * csect1 = reaction rate = (number flux)*(cross section) | ||
