[Mesa-users] ppisn: neutrino luminosity as a threshold for turning on Riemann solver

[Francis Timmes]

dear jing-ze,

this is an excellent experiment for you to run!
then you'll be able to quantify the differences.

In Merchant 2019 paper it's set to be 10d0 (10^10 solar luminosity), whereas in the test_suite it's 9d0. If I want to delay the turning on of Riemann solver and set this value to be 12d0, will the results be much different (e.g., give very different BH masses or make a PPISN event become a direct iron core collapse)?
