Why do the labels for right ascension and declination overlap in the middle of the image?
Roughly speaking, the declination lines are labelled where they intersect the “median” line of right ascension (ie, the line of right ascension closest to the center of the photograph), and the right ascension lines are labelled where they intersect the median line of declination. Unfortunately, at the point where the two median lines intersect, both labels appear, overlapping. I hope to fix this at some point. 3.2. The annotations appear in an odd color. Why? Annotations are created using PHP’s JPEG image creation features. I haven’t found a way to get these to be of a consistent color (there’s supposedly a way to do it, I just haven’t gotten it to work), so I just tell PHP to use “the color closest to white”. 3.3. When using the chart annotation, some of the chart dots look like stars. I’ve considered several ways of avoiding this (changing the dots to “x”s, changing the color of the dots, removing the dots entirely, etc), but haven’t really found a good way around this.
