Re: Moon question

Guy Schwartz asked-
Assume the following data:
HP of the moon on a given hour on a given day is 55.0
The Ha (Apparent Altitude) is 31 deg 37.1 min. Therefore using the
altitude correction tables 0-35 deg for the moon the first correction
is 58.2.
Since this is a Lower Limb site, sliding down to the second correction
we have 1.9 for an HP of 54.9 or 2.2 for an HP of 55.2.
The question
is it OK to interpolate here and use 2.0 or go with 1.9 since 54.9 is
closer to 55 than 55.2?
================
Interpolate.
Whenever you can see it will do some good, as in this case,
interpolate.
