/*
	Name:		find_type42
	Purpose:	print the channel coefficients response table to standard 
				output
	Usage:		void find_type42 ();
				find_type42 ();
	Input:		none - uses information in globally-available structure
	Output:		none
	Externals:	type42_head - 1st entry in table; defined in structures.h, 
					allocated in globals.h
	Warnings:	none
	Errors:		none
	Called by:	print_response
	Calls to:	none
	Algorithm:	print the contents of the structure to the standard output.
	Notes:		The structure is a linked list; type42_head is the first member
				of the list
	Problems:	none known
	References:	Halbert et al, 1988; see main routine
	Language:	C, hopefully ANSI standard
	Author:		Stephane Zuzlewski
