COLLABORATION ATTRIBUTIONS

    Below there are two examples of Data Point Distribution (DPD) and their relationship to the Designated Artist Target Zone (DATZ). Both examples appear in a similar graphic format to that which appears in the various Catalogue Raisonnés.
    The image designated as rbc-986 shows the results typical of a collaboration painting. Note that eleven of the IDP are located within the DATZ for Peter Paul Rubens. All eleven IDP form a tight cluster within the DATZ. Two IDP are barely visible at the edge of the graphic. What appears to be only a short distance from the DATZ is actually much farther away than is apparent due to visual compression of the graphic. The farther the distance from the DATZ, the greater the compression of visible space.
    Veritus normally uses sixteen IDP for its evaluation. Because of the initial results, Veritus plotted an additional eight IDP. A cluster of twelve IDP fell within the DATZ of Sir Anthony van Dyck. In effect, there were two DPD centres. Thus, this painting is clearly a collaboration work between Peter Paul Rubens and Sir Anthony van Dyck.

    The image designated as rcr-652 shows the results typical of a collaboration painting. Note that twelve of the IDP are located within the DATZ for Rembrandt van Rijn. All twelve IDP form a very tight cluster within the DATZ. Three IDP are barely visible at the edge of the graphic. What appears to be only a short distance from the DATZ is actually much farther away than is apparent due to visual compression. The farther the distance from the DATZ, the greater the compression of visible space.
    Veritus normally uses sixteen IDP for its evaluation. Because of the initial results, Veritus plotted an additional eight IDP. A tight cluster of ten IDP fell within the DATZ of Jan Lievens. In effect, there were two DPD centres. Thus, this painting is clearly a collaboration work between Rembrandt van Rijn and Jan Lievens.
