Study 000208: ACRONYM: iuu_slot_sns_ar_02 Intended to take sit-and-stare observations of an active region or quiet Sun for a large sample (20) of clean spectral windows. Spectral windows are selected for their spectral purity, diagnosed from previous 40" slit FULL CCD observations. In order to be able to retrieve a sufficiently large number of spectral lines with wide temperature coverage, JPEG98 compression is used. Spectral width is 48 pixels to account for the wavelength orbital drift. TARGET : Quiet Sun or Active Region EXPOSURE TIME : 30s SLIT : 40" FOV : 40"x512" SPECTRAL WIND.: 20 Note: USES JPEG COMPRESSION. WARNING: High data rate resulting from reducing the JPEG compression factor
