Exercises
Access files here (images/spectra for reduction)
IRAF packages that should be loaded at startup (i.e. put this list
at the end of your login.cl)
→ packages.txt
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
