Preparing Red‐Green‐Blue Images from CCD Data
Preparing Red‐Green‐Blue Images from CCD Data
We present a new, and we believe arguably correct, algorithm for producing red‐green‐blue (RGB) composites from three‐band astronomical images. Our method ensures that an object with a specified astronomical color (e.g., g−r and r−i) has a unique color in the RGB image, as opposed to the burnt‐out white stars to …
