Corrected Dolan et al radial dose function values in g(r) graph for 6711 seed clerical error

R. Taylor
g(r) data have been renormalized so that gfit(1 cm) = 1.000 By renormalizing the g(r) data so that gfit(1 cm) = 1.000, we avoid giving undue importance to the point r = 1 cm in the normalization of the radial dose function, instead normalizing the data using a fit over the entire range of data. This means that the raw g(1 cm) data may no longer be exactly equal to unity, although it is always within 0.4 %. If one wishes to obtain the raw g(r) values, simply divide the tabulated g(r) values by the tabulated value of g(1 cm).

TG-43 Parameters and Primary and Scatter Separated (PSS) doses for 192Ir and 169Yb sources have been added. These calculations are discussed in our paper titled "EGSnrc Monte Carlo calculated dosimetry parameters for 192Ir and 169Yb brachytherapy sources" which has tentatively been accepted for publication in Med. Phys.

Labelling errors in the 00.00cm PSS dose data plots were corrected for the 192Ir GammaMed, 12i, HDR, 192Ir GammaMed, Plus, HDR, 192Ir Varian, VariSource (classic), HDR, 192Ir GammaMed, 12i, PDR, and 192Ir GammaMed, Plus, PDR sources. The HDR sources listed had the labels for scatter dose and total dose reversed and the PDR sources listed had both total dose and scatter dose labelled as scatter dose.

The files anisotropy_section.php and scatter_data.php were updated to avoid errors in labelling plots caused by seed names including strings like 00.30. The search for strings like 00.00 was replaced with 00.00cm to ensure that only the end of the file name was taken.

The scatter_data.php file was updated to display accurate alt-tags for PSS dose data plots. The PSS dose data plots were displaying "Anisotropy function" upon mouse over.

Qualification added to microSelectron v1 (classic) source regarding the encapsulation material. Steel should have been of type AISI 316L rather than AISI 304, however the differences in composition and density are negligible. Thank you to Thorsten Sander of NPL for pointing this out.

Randy Taylors name removed as contact. Randy Taylor decided to move on to other things. We greatly appreciate all he has contributed to the CLRP.

Fixed minor errors related to naming of Nucletron PDR sources. The source Nucletron, microSelectron v1, PDR was removed as it was obsolete. Nucletron, microSelectron v2, PDR was renamed Nucletron, microSelectron-PDR v1. The microSelectron-HDR v2 source was stored again as microSelectron-PDR v2. And index.php was updated to so that the Nucletron sources conformed with the Nucletron naming conventions.

In description of Ir192 HDR Flexisource changed diameter to radius for the 0.355 mm hollow section. Thanks to Mathieu Plamondon of Laval for pointing out this error.
