notes

Perform a review of the online result and assess if it is sufficent for sending a skymap. Results copied from /home/pe.o4/O4c/S250221eb/online/bilby Instructions can be found [here](https://git.ligo.org/pe/O4/o4b-rota/-/wikis/Review-instructions). When this file is updated add the contents as a comment on the relevant git issue. Automatic online PE run succeeded Retracted due to glitch in Hanford Calibration in Hanford unusual, m1 high, support for negative chi_eff, but otherwise results look sensible (a useful reference for how glitches can look in PE)
