3.4 CALIBRATION AND ADJUSTMENTS
For precise determination of stellar magnitude, the filters used in the SSP-4 must be calibrated
with standard stars. The procedure for doing this is beyond the scope of this manual and the user
is referred to the IAPPP organization and standard texts on photometry. Simple determination of
filter correction factors can be made by using a close pair of stars with a wide color temperature
