Hi! I am running my data with SGAT, but I am not sure which zenith should I use in the thresholdPath and which in the Estelle model. I think I should use the median deviation zenith in the thresholdPath and the zero deviation in the Estelle?

Also, which could it be the effect of running my calibration during the spring equinox?

Thank you in advance!!!

That is correct, median deviation for thresholdPath, since it ignores the error structure and zero devotion for the Estelle model.

Running calibration during the equinox ist actually a good thing, if you have enough time around the equinox. Given the structure of errors around the equinox, estimates of latitude are very sensitive to zenith angles (sun elevation angles).

Hope that helps,

Simeon
