SUMER study #1848: Quiet Sun scan around 1542 Å
Overview
- date, time: 08.Mar.99, 15:20 - 19:20 UT
- field of view: 44 arcsec E - 64 arcsec W, 30 arcsec S - 270 arcsec N
- slit: 1.0 arcsec x 300 arcsec (number 2)
- raster step size: 1.13 arcsec (3 elementary steps)
- exposure time: 150 seconds
- telemetry: 97 images of 512 spectral x 360 spatial pixels (format 38)
- compression: quasilog-min-max (method 5)
- wavelength: 1542.00 Å on reference pixel 510 of Detector A
- rotation compensation: after complete scan, corresponding to
0.75 arcsec after 296.934 seconds
- binning: no spectral, no spatial
- on-board flat field correction: no
Remarks: The scan was performed in west-east direction. Therefore, considering
the Solar rotation, it covers more space (145 arcsec) than the nominal pointing
indicates.
