SUMER study #134: East Limb Network Evolution
- date,time: 06.Mar.96, 00:35 UT - 02:46 UT
- field of view: 1054 - 828 arcsec E, 150 arcsec N - 150 arcsec S
- slit: 1.0 arcsec x 300 arcsec (number 2)
- raster step size: 0.75 arcsec (2 elementary steps "Schmierschritt")
- exposure time: 5 seconds
- telemetry: 5(scans)*5(lines)*301 images of 1 spectral x 360 spatial
pixels (format 18)
- compression: Lemaire's addition scheme (method 16)
- wavelengths:
790.20 Å on reference pixel 120 of Detector A
786.48 Å on reference pixel 297 of Detector A
1563.79 Å on reference pixel 515 of Detector A
780.30 Å on reference pixel 591 of Detector A
1548.19 Å on reference pixel 885 of Detector A
- rotation compensation: 0.75 arcsec after 1447 seconds
- binning: no spectral, no spatial
- on-board flatfield correction: no
Remarks: The same area was scanned five times in alternating directions.
Only the first scan is shown here. - There is no spectral information, because
the data were compressed on-board by integrating a 50-pixel-spectral window
(approx 2.1 Å in first order, 1.05 Å in second order) around the
commanded wavelengths.
The study was initiated by P. Lemaire (IAS).
