### We’ve released 16 additional channels from O3 !

Researchers at IAS made a request for some additional O3 data, and we’ve made these data available. The data release is intended to support studies of noise cleaning methods, and is available in frames with the tag `AUX_CLN`. It builds on a [previous O3 auxiliary data release](https://ask.igwn.org/t/new-data-release-o3-auxiliary-channels/470). We hope this will be useful for your research.
