I am trying to write a script that will plot a 2d histogram of effective volume versus two of ShelfMC's parameters.
The script prompts the user for which two parameters (out of five that we vary in our parameter space scan) to plot along the x- and
y-axes, as well as what values to hold the other 3 parameters constant at. It then collects the necessary root files from simulation results, generates |

Hi,
I've attached a copy of some of the work I did over the summer on ray tracing and how I did it. Please let me know if you have any questions.
PS The plots are sidewards for some reasons. Sorry about that. |

Attached are instructions and scripts for carrying out a parameter space scan with ShelfMC, the simulation package for the ARIANNA detector.
Because some of the plotted outputs looked like colored stripes and did not offer any insight into how effective volume changed with some variables,
I made some changes to the simulation and plotting scripts so that different maximum, minimum, and increment values can be chosen for each variable. Now |

Hi All,
We need to revive the icemcQC and AraSimQC pages, and I thought that in the meantime we could keep a list and/or associated code for plots we'd
like to see go in there. |

With Brian's help, I am writing the python serial commander code used to control and troubleshoot the ARAFE master board. I have worked on it for
about 2 weeks so far, and progress is slow but measureable!
Recently, we are powering on a channel and are able to measure the clock on an ARAFE board we attach to it. |

This is a "bank" of mac addresses that we obtained for the lab. They were taken by Ian Best (one of Jim' students) in summer 2017. We purchased
25 AT24MAC402 EEPROMS (https://www.arrow.com/en/products/at24mac402-stum-t/microchip-technology) and used a SOT-23 breakout board and a bus pirate to retrieve
their internal mac addresses. |

I've been working on a calculation to generalize the form factor (Eq. 26 of attached paper) to include particles from wider lateral distances from
the cascade axis. Formulae that were single terms now become sums, as I choose to model the contribution from wide-ranging particles as a sum of
exponentials rather than a single exponential distribution. See attached version of the paper (you can clone it using git: kingbee.mps.ohio-state.edu:/home/hanson.369/AskaryanPaper). |

This document summarizes my project with karoo machine learning where I used it to model the inelasticity distribution from the Connolly
et al. cross-section paper. I plotted the four distinct functionst that karoo gave me out of a 100 against the data. The parameters I used were:
tree depth=5, number of generations = 20 and coeffecients ranging from 0.1 to 0.5. I had issues getting each of the functions to fit the |

Hello! Back to ARA analysis.
Whenever I attempt to decide if a signal was an incoming plane wave, I compute the planarity of the event by summing cyclically the time-differences
in adjacent channels that form a polygon. For square polygons, this looks is like summing the time-difference between channels A and B, B and C, |

See the attached papers. I wonder if we could look for these with ANITA and distinguish between natural and artificial origin.
Here are some estimates that I did last night.
The paper quotes that for an FRB at a distance ~10-20 kpc, we would see at S_nu=10^10-10^11 Jy where 1 Jy=10^-26 W/m^2/Hz. |

Hello! See the attached report relating the compressibility of firn, the density profile, and the resulting index of refraction profile.
The gradient of the index of refraction profile determines the curvature of classically refracted rays. |
