Tasks for GJH

[gully]

From I. Czekala:

• Fig 10: What is the difference between red and blue spectra? If this information isn't obvious, it would be nice to have in the caption or as a legend on the plot.

From G. Somers:

• Fig 10: consider error bars on the TiO indices
• Fig 11: Plot legend for the various datapoints and lines?
• Put an unique entries for L in the "historical" table for our two different estimates for the cool component.
• Re: Fig. 9: How exactly did you construct the models you are comparing them to? ... Issues w/ PMS bolometric corrections might also come into play. ... contribution of plages/faculae (hot spots). Perhaps these are messing up your derived T's in a 2 zone model, and thus your prediction for what the cooler spots should look like is off.
• Explain why luminosity stays about the same in HR diagram

Figure 9 caption: The observed optical colors of LkCa 4 from Grankin et
al. [32],
compared with predictions from converting V -band brightness to a cool spot
filling factor and subsequently calculating colors from main sequence colors
and bolometric corrections of Kenyon & Hartmann [50](purple lines).

change KH95 to \citet{Pecaut13}.

Section 4.2, para 1, immediately following "pre-main sequence colors": The
photometry is obtained from the colors of 4100 K and 2750 K photospheres,
as obtained from main-sequence colors listed in \citet{Pecaut13}. The
time-dependent color is then calculated by combining these two components
based on their visible areas, as inferred from the $V$-band brightness.

There are some comments embedded in S Alencar's draft that you might want to double check on.

I assume we're good on these?
