......@@ -21,11 +21,6 @@ the following changes have been made:
- The minimal mass of SNII stars has been raised to 8 Msun (from 6).
- The SNII feedback delay is done by sampling the stellar age
distribution and not using a fixed delay of 30 Myr any more.
- The Magnesium yields from SNII stars have been boosted by a
factor of 2.
- The delay time distribution of the SNIa has been changed to a
power-law of slope -1 (instead of the exponential model) and
the rates have been renormalized.
- The black hole accretion rate is now limited to 100% of the
Eddington rate (from 100/h = 150 %).
