A Lossy Method for Compressing Raw CCD Images
Mid-Infrared Observations of V838 Mon (2006)
Costero , R., Gómez , L., Watson , Alan M.
We present 8-13 Um narrow-band photometry of the peculiar star V838 Mon in 2002 September. Our spectrum is consistent with a simple power-law spectrum, although a spectrum with excess emission...
