The measured altitude was less that the computed altitude. In general, error=measured value-true value. correction=true value-measured value=-error. Examples: dip correction in the almanac is always negative. Lower limb correction is always positive and upper limb correction always negative. Index error has the opposite sign of the Index correction. And so on.
