I see that my detector photo below and initial results have a bad link. I just found how to attach rather than link images, so this one should be more reliable. the Lead sides and bottom are now 35 mm / 1.4" thick, and reduce the overall background by 32%, so anything from above should have been detectable.

Raw count summaries for Iridium fragments 34073,34356,34499 and 34498
December and July are being re-processed. These fragments have the highest counts for the available data set, and have been consistently on the top of the list. I will be attempting to produce clear graphics to show the contrasting levels for all fragments. Also, the data used only represents 1/3 of the total available data. the reminder of which has yet to be downloaded and processed.
