Abstract

We present the public release of the low-frequency atlas of continuous gravitational waves, covering signals with frequencies from 20 Hz to 200 Hz and frequency derivatives from −5×10−11 to 5×10−11  Hz/s. Compared to the previous atlas releases, this version demonstrates significant improvements in sensitivity and sky resolution. In the most sensitive region, even the worst-case upper limits on gravitational wave strain are below 10−25. The atlas data are being released ahead of the completion of the full follow-up analysis.
