This section provides the keys to the information necessary to understand our data presentation. The raw data obtained during the examination of a painting is filtered and collated. This information is then translated into data points. Veritus elected to use the data point format because this format is easily decoded through non-technical human interaction.
    Veritus desires for the results of the technological investigation to be as unambiguous and user-friendly as possible. To this end personnel at insurance companies and banks, as well as jurists, auction houses, gallerists and collectors do not require extensive training to understand or apply the results of the graphic presentations.
    Information is presented graphically as Individual Data Points (IDP) in what Veritus identifies as a Designated Artist’s Target Zone (DATZ). The artist’s name always appears in the upper right corner of the graphic describing the DATZ. The sample DATZ is the white area marked in red "Artist Target Zone" on the sample graphic that appears below.
    Digital information is collected then filtered, collated and converted into IDP. These IDP will form a pattern called a Data Point Distribution (DPD). The DPD is then compared to the known DATZ for different artists to determine the authorship of the painting.

    The DATZ is defined as a white area which fades into grey. The area that appears in white is the definitive area of the given artist. The fading grey area represents a proportional loss of confidence for attribution. The area in solid grey represents areas of confidence that exist for other artists. Thus, a convergence of points in a target zone establishes the attribution.
    It is also very important for the viewer to recognise that Veritus uses an algorithm to proportionally compress areas outside the DATZ. This compression begins at the start of the fade to grey. Veritus compresses the graphic to facilitate evaluation by the viewer. If compression were not used, many IDP outside the DATZ would not appear on the graphic. Even with compression many IDP still fall outside of the graphic. Thus, an IDP that appears to be only a short distance from the DATZ is actually much farther away than is apparent. The farther the distance from the DATZ, the greater the compression of visible space.
    The graphic appearing to the immediate left shows a full graphic without compression, reduced to a size so that the external dimensions are the same as the proceeding graphic. The reference lines are removed since they would mask the DATZ for the viewer.
"...the DATZ employed is of optimum size for reliable inter-
pretation and
    Data points will sometimes appear in areas that provide inconclusive results. The method by which Veritus deals with these inconclusive results is listed with the illustration of the event.
    The centre point of the target area is determined using standard statistical methods of analysis. The point at which there is no overlap with the information collected from other artists determines the target area chosen for each artist. The size of the target area, therefore, varies slightly from artist to artist. Veritus’ research has determined that the DATZ employed is of optimum size for reliable interpretation and attribution. For the purposes of simplifying the interpretation of the data, the scale of the target zone is adjusted to provide a uniform presentation.

By following this procedure, you will understand the manner by which results are interpreted. Consequently, you will be prepared to interpret the information presented in the various Catalogue Raisonn�s to your own personal satisfaction.
