Stars
# Faint stars (19<=g<22): 41 in total. Median combined. Inner profile R[pix]<9, outer profile R[pix]< 200 and curve-of-growth up to 250 pix
# Bright stars (16<=g<19): 52 in total. Median combined. Inner profile R[pix]<9, outer profile R[pix]< 200 and curve-of-growth up to 250 pix
# Saturated stars (g<16): 29 in total.Median combined. Inner profile R[pix]<9, outer profile R[pix]< 200 and curve-of-growth up to 250 pix
# PSF created by average combining and scaling to the median bright, faint and saturated star: inner profile R[pix]<9, outer profile R[pix]< 200 and curve-of-growth up to 250 pix
Images in the 1st row: faint, bright and saturated star
Each image is 501 x 501 pix large ~ 200 arcsec x 200 arcsec (radius ~ 100 arcsec). Radial profiles and curve-of-growths given above.
Final PSF by average combining previous three images and scaled to median
Central part of the saturated star masked during combining.
Joining stars
Points from SMA>7 & SMA < 17 are used to create an overlap region for fitting: (1) inner part where saturated core is replaced by bright star inner region; (2) full extent of the PSF with inner region replaced by bright, unsaturated star; (3) sliding median is used to replace part of the profile with a bump (blue points -> violet points) and further away again the saturated star radial profile is used.
