  •  Comment Sorry, this is not a spectrum but a depiction of absorption lines in the light coming form the Sun. Either we like it aesthetically or not but no exact information can be taken from the image alone (there is no frequency scale), and the text doesn't explain the meaning of the absorption lines.

    • Don't know how it's called in English, but in Polish it's spectrum of absorbtion. This image is enough for qualitative analisys of this physical phenomenon. --WarX 18:07, 28 January 2007 (UTC)[reply]
  •  Oppose The scale is not needed; it is clearly explained at the NOAO source from which the image comes (it's about 70 nanometres per band). This image is generated from numeric data, it's not a photograph. You can ask any size to NOAO which will compute the image from their data. The only bad thing is that i's in JPEG format, so this creates artefacts when seen at its maximum resolution. The image would be much better in PNG format (because applying any filter to it would be completely inappropriate! unfortunately the JPEG format is itself a low-band pass filter within each 8x8 cell, and not so cute to see). The NOAO certainly has much better data but keeps it for its sales or scientific research exchanges, this image is just a demo of what they have. Verdy p 01:17, 6 February 2007 (UTC)[reply]
