→ packages.txt

Class #01: Create an unsharp mask image of a barred galaxy

Class #02: Measure the brightness of two stars in different filters, and correct for the different detector efficiency

Class #03: Remove a galaxy to see the noise created by its photons

Class #04: Calculate read noise and gain, using calibration images

Class #05: Start reducing an imaging dataset

Class #06: Continue reduction – masterdark & masterflat

Class #07: Continue reduction – apply calibration images; fringing

Class #08: Continue reduction – create superflat & try to remove fringing

Class #09: Continue reduction – subtract background & create weight image

Class #10: Finish image reduction & start reduction of spectra

Class #11: Reduction of spectra: basic steps & wavelength calibration

Class #12: Reduction of spectra: sky subtraction & flux calibration; fringing in spectra

Class #13: Airmass correction & flux calibration of imaging data.

Class #14: Pixel scale & equivalent width.

Class #15: PSF measurement & image coordinates
