Reply To: Sight Reduction 229 Interpolation tables

[Tyler Szwarc]

Hi Dmccue,
It is possible to use the 229 Interpolation tables when LHA is 0, but in this specific situation, you don’t actually need them. When LHA is 0 and d = +/-60, your HC correction is simply the Dec. Inc, which is then added to or subtracted to Hc (as determined by the sign of d).
Hopefully I understood your question correctly; let me know if I didn’t!
