'Slow Nuclear transients' filter results
'Slow Nuclear transients' filter results
Based on the r0b_lvra filter, designed for slow nuclear transients. Requires the max r band flux is at least twice the min, and the latest detection is at least 30 days older than the earliest, and the latest flux is higher than the mean flux (i.e. the object has not declined too far) ordered so the latest is first. The filter is streamed via email .
