[PARAMETERS]
int     | CDPtype | = |   | 	
string  | a | = |   | 	
int     | extend | =4 |   | 	trace extension 
float   | h0 | =0. |   | 	reference offset 
bool    | half | =y |  [y/n] | 	if y, the second axis is half-offset instead of full offset 
string  | mask | = |   | 	auxiliary input file name
int     | mute | =12 |   | 	mute zone 
string  | offset | = |   | 	auxiliary input file name
string  | s | = |   | 	auxiliary input file name
bool    | slowness | =n |  [y/n] | 	if y, use slowness instead of velocity 
bool    | squared | =n |  [y/n] | 	if y, the slowness or velocity is squared
