Greetings,
Am pretty sure me only had that kind of a problem in calcs, but, anyway, let me share it with you. Just in case.
Using intercept method. Getting wrong fixes . Checked anything a few times, every adding/subtraction. By the way, I knew what the right fix should be. Just doesn't work. Then recollected oldl engineering rule # 0: If something is going wrong-check constants. Anyway, found out that when corrected Declination for proper GMT I added the correction "d" without giving any thought why I am doing it. Just added. In my case it was about 10'. Then, when I checked NA page and looked down the page, I realized that Decl. is decreasing. And as soon as I subtracted "d", everything worked fine. Again, I'm sure you know it and pay proper attention to the "tendency" in Decl. to put a correct sign to "d". Then, when you are using , let say, Pub.229, and correct Hc-then the error in "d" for Decl. does affect Hc. And eventually intercept itself.
Never I imagined this kind of error would affect the intercept so much. In my case it did.
