SKYLINER-Removes a sky spectrum normalised the 5577 [OI] line.
- Description:
- Removes a sky spectrum normalised by the height of the 5577 [OI]
emission line.
- Usage:
- skyliner in sky out
- Parameters:
- IN
- The one- or two-dimensional spectrum to be sky-subtracted.
- SKY
- The one-dimensional sky spectrum. It must not contain bad
pixels as they could affect the estimation of the [OI] line
strength.
- OUT
- The sky-subtracted one- or two-dimensional spectrum.
- Source comments:
None available.
