Explanation	Paper scaling records	35 mm film records	16 mm film records	Digital records

(e) =	placed after a station name means other equipment, besides an ionosonde, is operated at this site.	IPS=IPS reference number	AGENT=	the organization responsible for operating the station (this reponsibility is shared at several sites).
		ESSA=Old WDC number.
DIP=	the dip angle between the horizon and the Earth's magnetic field.	SPLIT=Split(0.5*gyro frequency)	4D-ID=	identity number found on 4D ionograms.
