This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 26 September 2013.
All research outputs
#21,637,273
of 32,950,213 outputs
Outputs from The Astrophysical Journal Letters
#6,406
of 8,451 outputs
Outputs of similar age
#239,195
of 364,775 outputs
Outputs of similar age from The Astrophysical Journal Letters
#56
of 132 outputs
Altmetric has tracked 32,950,213 research outputs across all sources so far. This one is in the 33rd percentile – i.e., 33% of other outputs scored the same or lower than it.
So far Altmetric has tracked 8,451 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 53.7. This one is in the 23rd percentile – i.e., 23% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 364,775 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 33rd percentile – i.e., 33% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 132 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 57% of its contemporaries.
