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.
