Scope out paper (letter?)

[jradavenport]

Currently the paper has 3 results:

• confirming the rotation period bimodality using the latest distances
• showing first attempt at tracing the bimodality/period structure as a function of distance
• showing width of main sequence with period gradient

and is drafted with 5 figures (the maximum for ApJL). Should we push forward with a short letter in the next week(s)? That is my preference - thoughts @kevincovey?

Paper draft taking serious shape now. 7 full pages at present

Really starting to get excited about this! Highlights (in my mind) include:

• the extent of the bimodality is quite localized. Given the galactic latitude of the Kepler field, this probably isn't due to scaleheight
• main seq. gradient is neat
• the spin for stars at the "top edge" of the main sequence is perhaps faster than we expect (if we assume they are very old), which could be used to validate the broken spin-down finding of Van Saders (tho don't want to make too strong a claim here, given first peek and small sample)

[jradavenport]

no no no, it IS due to scaleheight. I have new plots that show it. I was being fast/loose here....

also, at 9pgs I think we're overflowing the "Letter" req, and am happy to think about this as a paper (why delete words?)
