The Nebula results page has been updated a number of times:

April 13, 2018

Birdie generation: change non-bary max frequency half-width from 50K to 20K. This way a non-bary birdie will fit in our 50K Hz window for non-bary multiplets.

April 3, 2018

Fix how birdie chirp rates are calculated.

March 15, 2018

Remove signals with excessive power (> 80% of FFT length).

March 8, 2018

Look for combined spike/gaussian and pulse/triplet multiplets, rather than each type separately.

January 31, 2018

Fix bugs in birdie generation. Fix bug in chirp pruning. Small fix to zone finder statistics.

January 1, 2018

Observation selection was using the wrong time interval. Calculate # of observation periods correctly. Fixes to multiplet finding; allow several multiplets per window. New multiplet-finding algorithm using smarter chirp pruning and observation selection.

October 24, 2017

October 6, 2017

September 30, 2017

New algorithm for period pruning. Use Eric's new formulas for multiplet exclusion time.

September 17, 2017

Apply spike drifting areas (triangles) to other signal types. Fix time bugs in birdie generation. Apply spike zones to other types as well.

August 7, 2017

Increase birdie power range to generate more signals. Make sure scoring includes all birdie pixels.

July 8, 2017

June 14, 2017

Chirp pruning: discard multiplet signals with inconsistent chirp rate/freq.
