Abstract
We present an erratum to correct an unintentional unit conversion error in our paper, J. Opt. Soc. Am. A 29, A216 (2012), and to update Tables 1 and 2. Here we publish the revised versions of Tables 1 and 2.

We have made an unintentional unit conversion error in our paper [1], which affected the contents of Tables 1 and 2. We measured illuminance in foot-candles, which we should have converted, shortly thereafter, to lux. However, inadvertently, we skipped the conversion step, and included instead, in Tables 1 and 2, data in foot-candles. In other words, illuminance in Tables 1 and 2 were published in foot-candles, when they should have been published in lux, as declared in our paper [1]. Since 1.0000 foot-candle is equivalent to, approximately, 10.7640 lux, values in the originally published Tables 1 and 2 were underestimated.

Table 2. Luminosity Ranges Used in the Experiments and Their Natural Equivalents
In Methods, Subsection 2.C of [1], Choice and Control of Luminosity, “Lux Light Meter, Extech Instruments Corporation” should be “Light Meter, Extech Instruments Corporation.”
Tables 1 and 2 of [1] should be replaced by these new Tables 1 and 2, in which values in foot-candles have been converted to lux.
Since these changes do not affect the results or discussion of [1], all conclusions of [1] remain true.
