7/31:
Compared Jen's new ugriz data to Clem's ugriz' data, plotted a new g'-r' vs g'-g transform. Then I overlaid all of Jen's matched data with data that had been further matched with kyle, to make this plot. Threw on the fit I derived 2 weeks ago, plotted it again. And the zoom. Now i took Dr. Morrison's data and plotted it.


8/01:
Used Dr. Morrison's data for both M13 and M92 to make plots showing the linear fit from SDSS and our transform for g'-r' Vs g'-g. Got a weighted average routine to run on tucker's data, matched the averaged points to zeljko, plotted the resulting transform graph (our earlier transform fit in orange).

looked at the plots when you use other transforms to get UBVRI. Used Tucker and Lupton's transforms (instead of ours and Lupton's) to make some plots: Tucker V Vs Tucker V - Stetson V, V-I residuals, B-V residuals, and B residuals. Next up was our transform with Zeljko's: V residuals, V-I residuals, and B-V residuals. Last but not least came Tucker's transforms with Zeljko's: V residuals, V-I residuals, and B-V residuals.


8/02:
Combined all of Tucker's USNO data, then matched it with Zeljko's stripe 82 data, to make new transform plots. The plots have our fits on them, as well as Tucker's: g'-r' Vs g'-g.


8/03:
Color coded my V residuals plot by magnitude and color, which shows that the BHB stars are very off. Transformed Clem's M13 data into ugriz, matched it with Stetson, then overplotted Zeljko's transform curve. Also, since Lupton's transform is for g-r, I used a separate plot for it.


8/04:
Realized I'd accidentally swapped B magnitudes for V magnitudes in my transforms from Tuesday, fixed all the graphs. Then did the transforms for M92. Here's Us and Lupton: V residuals and V-I residuals, Us and Zeljko: V residuals and V-I residuals, Tucker and Lupton: V residuals and V-I residuals, and Tucker and Zeljko: V residuals and V-I residuals.

Went back to spectra, plotted g-r Vs K' for M13, with different colors showing different error ranges.
