Unless otherwise noted, all plots below use CMD cuts (to weed out field stars), error cuts of .02, and a sep cut of 6

Finished redoing the plots from last week, they're on last week's page, at the bottom. Looked at M92's u'-u graph, a quadratic and a cubic function to it, just for the hell of it. Started to plot transform overlays between M92 and M13. Here's g'-g. Moved to making histograms, to show the difference between the medians of M13 and M92. Here's the BHB (g'-r' < 0), the turnoff (.175 < g'-r' < .35), and the main sequence (g'-r' > .4). Next plotted the same things (down to the same limits) for r'-r: BHB, turnoff, and main sequence.


7/05:
Made a CMD for M92 in ugriz, so I could tell where to make my cuts. Figured out where to make my cuts for M92, which was offset from M13. Remade the g'-r' transforms for M92: u'-u, g'-g, r'-r, i'-i, z'-z.

Flipped back to M13, did the same thing for those transforms as I did for M92: u'-u, g'-g, r'-r, i'-i, z'-z.

Now went to overlays. Added u'u, r'-r, i'-i, and z'-z to g'-g from Monday.


7/06:
Moved to color-color plots. Made several for M13: u-g, g-r, g-i, and r-i.

Next, I overlaid PM members onto the transforms for M13: u'-u, g'-g, r'-r, i'-i, and z'-z.

Back to M13 color-colors - this time I made residuals for the above plots: g-r, g-i, and r-i (u-g is so bad it's useless to plot a residual).

Got new data from Zeljko, plotted a comparison of the residuals of g'-r' Vs. g-r for M13, M92, and Zeljko's field stars (which have no error or sep estimates, and are not a part of a cluster-so no CMD cut either).

Took the linear fit from the full 0 to .2 degree field for M13, then plotted the residuals of the individual .05 degree annuli to the line and found the median residual. Did the same for r'-r. Looked at M13's turnoff and giant branch next, plotting the same things for g'-g and r'-r again.


7/07:
Did the median residual plots for M13's i'-i and z'-z on the horizontal branch, and for i'-i and z'-z on the turnoff/giant branch. Figured u'-u was a lost cause, so didnt bother making those plots.

Went to M92, made g'-g and r'-r for the HB.

Spent quite awhile trying to match up the field stars, but I finally got it. The result is a field/M92/M13 transform overlay.
