| warren | "Hmm, how did you use your white front bike light to calibrate? Surely it's not a compact fluorescent bulb? " | Read more » | about 9 years ago | |||
| warren | "Hmm. So I'm wondering if part of the fit problem is because we're simply comparing intensity at the 14 points and 13 troughs. Take this example: ..." | Read more » | about 9 years ago | |||
| warren | "Cool, thanks! I was mainly looking for a citation for the most common forms of Hg, and/or a clear reference for which is found in CFL bulbs. But aw..." | Read more » | about 9 years ago | |||

| warren | "Hmm. I guess there are pros and cons to each approach. I agree that the 546 line doesn't result in a great linear calibration -- some end up about..." | Read more » | about 9 years ago | |||
| warren | "OK - I'm adapting the calibration slider to use the photoshop-corrected version of the Snow Sky spectrum. I read the blue 436 peak at 210px from l..." | Read more » | about 9 years ago | |||

| warren | "Would you be willing to try a recalibration using the 436/546 lines as a starting point? Would that be useful as a point of comparison? Also - I b..." | Read more » | about 9 years ago | |||

| warren | "If it's helpful, we can probably ask some of the OTK beta participants for one, since a couple have access to lab spectrometers. In your image/ima..." | Read more » | about 9 years ago | |||
