Variance Map Floor Tests
6 July 2001
Plots (columns in table):
-
Reduced Chisquare VS Profile Fit Magnitude
-
PSF Sigma VS Profile Fit Magnitude
-
Reduced Chisquare VS S/N
-
Chisquare Histogram. (Normalized.)
-
(PSF Mag - Standard Aperture Mag) Vs Y (Scan Angle).
PSF ID segment boundaries marked.
-
Reduced Chisquare Vs Y (Scan Angle).
PSF ID segment boundaries marked.
-
Profile Fit Magnitude Vs Standard Aperture Mag
-
Background Vs Y (Scan Angle)
-
Histogram of Profile Fit Magnitude
-
(PSF Mag - Standard Aperture Mag) Vs PSF Mag
-
Sigma PSF Mag Vs Y (Scan Angle).
PSF ID segment boundaries marked.
-
Sigma PSF Mag Vs Sigma Std Aperture
-
S/N Vs PSF Mag. Blends are overplotted "+".
-
S/N Vs PSF Mag, for non-blends, passive deblends, active deblends, and mixed,
separately in four panels.
NB sometimes the .gifs may come out white-on-white, and appear blank.
Changing the image from 8-bit to 24-bit mode with xv should fix it.
