  We demonstrate a breakthrough in the capabilities of robust, broad-parameter
space searches for continuous gravitational waves. With a large scale search
for continuous gravitational waves on the O1 LIGO data, we prove that our
Falcon search achieves the sensitivity improvements expected from the use of a
long coherence length, while maintaining the computational expense within
manageable bounds. On this data we set the most constraining upper limits in
the gravitational wave amplitude in the band 100-200 Hz. We provide full
outlier lists and upper limits near 0-spindown band suitable for analysis of
signals with small spindown such as boson condensates around black holes.
