 Dorsal full body images of subspecies of _Heliconius erato_ and _Heliconius melpomene_ (18 subspecies total).
 There are 960 images with 320 specimens (3 images of each specimen: Original/ Bird transformed/ Butterfly transformed)
 The original images are low-resolution RGB photographs (photographs were "cropped and resized to a height of 64 pixels (maintaining the original image aspect ratio and padded to 140 pixels wide)"(Hoyal Cuthill et al., 2019)).
-These low-resolution images were then transformed using [AcuityView](https://cran.r-project.org/web/packages/AcuityView/index.html) with estimates of acuity from [AcuityView 2.0](http://www.empiricalimaging.com/knowledge-base/acuityview/) and [Land, 1997](https://www.annualreviews.org/doi/10.1146/annurev.ento.42.1.147).
-Users should know that since Land (1997), more recent estimates of insect visual acuity have been created.
