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 that the output from GetGain_1D_OutZero is negative, which leads to -nan values from GainToHeight because it takes the square root of the negative values from GetGain_1D_OutZero. We aren't quite sure why we're getting those negative values (we know which variables and operations are giving them, but not why they're so different for some small individuals), but we think a solution is to set any negative output from GetGain_1D_OutZero to just be 0, since they're all lower than the lowest frequency in the band of interest anyway.</td> <td>We can implement the change to fix these effective volumes. I'm still concerned that we're getting high effective volumes from this, when I would have expected the resolution to have decreased effective volumes for all of the small antennas. We should also be testing this with the actual Bicone to see how it changes that effective volume.</td> </tr> <tr> <td>Alex P</td> <td> </td> <td> </td> </tr> <tr> <td>Eliot</td> <td> </td> <td> </td> </tr> <tr> <td>Leo</td> <td> </td> <td> </td> </tr> <tr> <td>Evelyn</td> <td> </td> <td> </td> </tr> <tr> <td>Ryan</td> <td>Possibly made progress with the roulette algorithm for paperclips. However I will not know for sure until I fix the syntax errors in the code ( which seems to be largely just me mistyping something up to this point). </td> <td>fix the errors in roulette.cpp and make sure the output is desired. Fingers crossed.</td> </tr> </tbody> </table> <p> </p> Encoding: HTML ELCode plain Suppress Email notification Resubmit as new entry
