Comparison of the brighter-fatter effect in the X and Y direction that are observed on CCD E2V-250, DECam and MegaCam.
|Instrument – wavelength||σ||Δσ@100 ke−||σ||Δσ@100 ke−|
|CCD E2V-250–550 nm||1.594||0.047 ± 0.002||1.622||0.052 ± 0.003|
|CCD E2V-250–900 nm||2.042||0.037 ± 0.0005||2.048||0.043 ± 0.0007|
|DECam–r-band (~640 nm)||1.709||0.022 ± 0.001||1.944||0.024 ± 0.001|
|MegaCam–r-band (~640 nm)||1.980||0.005||1.960||0.006|
Notes. Comparison between the two columns shows that the amplitude of the broadening is steeper in the Y direction than in the X direction. It should be noted that the values that are estimated for the MegaCam instrument are arguable because they depend on the range where they are adjusted.
