these are the two papers on which my understanding of line arrays is based.
please note that for the 2nd ( JBL ) paper all the graphics / charts / diagrams are at the very end so if you browse the first few pages it may look like it is nothing but formulas and will be completely unreadable but actually there are references to charts in that text, and in fact i suggest looking over the charts FIRST and THEN reading the main text.
whatever idiot wrote that paper didn’t understand how human mind works. we need context for information in order to absorb it. the charts provide the context. putting them in the end was really dumb but if you look at them first and realize you don’t need to understand every formula you will be able to get through the text and understand something.
well, if you’re a genius like me anyway.
