Clarify edges of band

Does J band exclude red-visible ? The diagram has a slightly thicker line on the X-axis that implies it might be from mid-visible to about 1.7 um ('centred on 1.25 um'). Unrelated to the atmospheric transmission bands shown in the diagram. - Rod57 (talk) 18:48, 26 October 2018 (UTC)[reply]

... Infrared astronomy says J band is 1.1 to 1.4 um (no source sadly) - I'll repeat here for clarity. Looks like J band is NOT an atmospheric transmission band according to the diagram used. - Rod57 (talk) 19:21, 26 October 2018 (UTC)[reply]
