The Tilma Under Infra-Red Radiation, Philip S. Callahan's 1981 monograph published by the Center for Applied Research in the Apostolate as part of its Guadalupan Studies series, is a technical infrared imaging study of the tilma bearing the image of Our Lady of Guadalupe, conducted by a research entomologist with expertise in infrared photographic analysis. Its strength is that it applies an independently checkable physical imaging technique to the artifact itself, published through a dedicated academic study series. Its limit is that Callahan's own interpretation of what the infrared findings mean for the image's origin remains contested among other researchers who have examined the same tilma, so this atlas cites the technical findings without treating his interpretive conclusions as settled.
