WebFWHM is Full Width Half Maximum. Take the maximum of your transmission peak, identify the points either side of the peak where the transmission is half the maximum, and the full width is the distance along the wavelength axis between those two points. It's just a way of measuring the width of a peak. The physical meaning will depend on the ... WebJun 20, 2024 · I would like to have a script that reads each .csv file and calculate the FWHM of the peak. I currently have a script that reads my .csv files from a folder and spits out information such as peak postion, area etc., so maybe its easier to just tag it onto that, however it is using peakfit, not fitpeak. WebJun 3, 2024 · FWHM is constant across a range of stellar magnitudes. Seeing disk diameter increases with decreasing magnitude (increasing brightness). The FWHM may be only 2-3 pixels, but the total number of pixels in the seeing disk (image) of a 'bright' star may be a couple of hundred in a well-focussed image. Roy frye leather ludlow sneakers

WebOct 20, 2010 · FWHM is still a good metric, but it would mainly capture issues of focus in this case. And you can look at any oblong shape of the stars as mentioned above. But the fwhm's won't be as consistent with changing intensity as they would with a more typical deep sky image scale of perhaps 0.5-1.5" per pixel. Frank WebMar 10, 2024 · A better definition would be something like: "The FWHM is the width of the point spread function of the image of the star at one half of its maximum value." Apart from its application to photometry on digital images, FWHM is a parameter applied generally to certain mathematical functions. Considered in this context (where no pixels can be ...
