foF2, the F2 layer critical frequency.

foF2 is one of the parameters seen consistently by both instruments and therefore provides a good comparison. For the months December 1993 to April 1994, the monthly percentage for common observations never drops below 75 percent. The correlation coefficient is highly significant with a percentage always in the high nineties. The gradient of the regression does not differ significantly from one, indicating that both instruments are seeing a similar F2 region on most occasions.
