Abstract

The article ‘How well can charge transfer inefficiency be corrected? A parameter sensitivity study for iterative correction’ was published in MNRAS 453, 561 (2015). We identified several incorrectly placed decimal points in Table 1 of that article that arose from presenting several curves in the related Fig. 2 scaled up by a factor of 10, as a visual aid. Table 1 details the parameters of a heuristic fit,

A+Daatan((logτ−Dp)/Dw)+Gaexp(−(logτ−Gp)2/2G2w),
A+Daatan((log⁡τ−Dp)/Dw)+Gaexp⁡(−(log⁡τ−Gp)2/2Gw2),

to the effects caused by a species of charge traps in a CCD, created by the degradation of its silicon lattice due to striking cosmic rays outside the Earth's atmosphere, on the measured photometry, astrometry and ellipticity of simulated galaxy images. In the published article, there is a typing error such that equation (14) lacks the negative sign in the argument of the exponential. The amended equation (14) above provides the correct form that we have been using for all fits.
