This data set contains calibrated level-2 images and spectra data from the Interface Region Imaging Spectrograph (IRIS).
UV images from IRIS telescope record observations of features as small
as 240 km (150 miles) on the sun every five to ten seconds at specific
temperatures, ranging from 5,000 K to 120,000 K (and up to 10 million
K during solar flares). This range allows observations of material
moving between the surface of the sun, called the photosphere, and in
the lowermost layers of the atmosphere, called the chromosphere and
transition region.
Spectra are obtained every two to thirty seconds along a slit (1/3
arcsec wide) of solar material at temperatures from 5,000 K to 10
million K, providing information on exactly how much light is visible
from any specific wavelength. This corresponds to how much material
is present at specific velociites, temperatures and densities.
The level-2 data is corrected for dark current, flat-field, and
geometric deformation, scaled to the same plate-scale, and packaged
into timeseries of slitjaw images and spectral raster scans.
