SODISM DATA
Full Image Macropixel Image
Solar images- Full images of size 2048x2048 pixels recorded at wavelengths 215, 393, 535, 607 and 782 nm (2 images / orbit)- Macropixel images of size 256x256 pixels at 535 nm with a cadence of 1 image each 60 seconds (helioseismology)
(size : 64x64 macropixels)
5Abdanour Irbah – 3/4 December 2008 – NICE
Solar limbs
SODISM DATA -II-
Samples of the whole SODISM image are extracted and present with limbsThese samples are used to follow instrument behavior on orbit
Solar limbs
- 22 pixels wide limbs recorded at 535 nm with a cadence of 1 limb each 120 s (helioseismology studies)
- 40 pixels wide limbs recorded at 215, 393, 535, 607 and 782 nm at a rate of 2 / orbit / wavelength
6Abdanour Irbah – 3/4 December 2008 – NICE
SODISM DATA -III-
- Flat field and Dark Signal images (size 2048x2048 pixels) : 1/day
- Dark Signal limbs (40 pixels wide limbs) : 4/orbit
- Double stars images (2 windows image of size 768x768 pixels) : 1/month
Dark signal image Flat Field image Dark signal limb Double stars image
