Maintenance will be performed on git.ligo.org, containers.ligo.org, and docs.ligo.org on Tuesday 25 March 2025 starting at approximately 8:30am PDT. It is expected to take around 30 minutes and there will be several periods of downtime throughout the maintenance. Please address any comments, concerns, or questions to the helpdesk.
For the "exact" calculation of substrate thermorefractive noise, pygwinc currently implements quadrature integration over wavevectors following P1400084 Eq. 17. However, BV04 Eq. E7 gives the solution in terms of a special function that is implemented in scipy.special
. The special function expression takes about 2 ms to evaluate, compared to 600 ms for the current quadrature integration.
