I wasn't available in the morning. I met with Amy and Alex P around 1 to talk
about how to use the AraSim function for throwing the same neutrinos to search for bugs in the loop. We want to compare three types of antennas we've |

Alex P and I kept working on finding differences in AraSim between antennas. We
still haven't found any and we've checked: electric field, maximum peak voltage, effective height, threshold (factor and offset), and the fft (and |

continue looking for the problem with the effective volumes. Amy asked us to investigate the phase responses coming out of XF. I posted the plots in the |

Worked more with Alex P on AraSim. We've found the cause of the low effective volumes. The
function GainToHeight in Report.cc uses another function called GetGain_1D_OutZero in Detector.cc. The problem is that for some small individuals, we get |

Ran the loop with the same individuals in each "generation" to test how decreasing
the grid size would affect the effective volume. Using individuals with lengths of 5cm, I startde with a grid spacing of 0.01 cm and kept cutting down |

Continued working to find the AraSim error. We think we're very close to finding where
the difference between the two individuals (one with nonzero effective volume, one with 0) is arising. We've pinned it down to a series of if statements |

the length of the antennas based on the minimum frequency, but right now I'm not sure how to find what that minimum length should be based on the frequency |

Yesterday we started a run of the database version of the loop. The goal was to use it to replicate the results from the run we
finished yesterday using the same parameters (NPOP=8, SEEDS=10, bicone separation = 0.05 cm). We initially ran into problems with the databse which we |

We may have found the error in the asymmetric bicone. It appears there may have been two problems. First, the setup for the simulation_PEC.xmacro
script in the asymmetric version appears to have been slightly different in that the positions of the cones, relative to the positions of the coordinate |

The arasim jobs I submitted over the weekend kept failing. I've been looking for the cause but I can't pinpoint it right
now. The issue arose on Friday when I overwrote the version of Report.cc on Eliot's user with the one we have on the databse branch (but I don't |
