SUMER study #2151: Raster scan at coronal hole
- date, time: 29.Oct.99, 01:01 - 05:03 UT
- field of view: 141 - 303 arcsec W, 430 - 540 arcsec N
- slit: 1.0 arcsec x 120 arcsec, centered (number 4)
- raster step size: 1.13 arcsec (3 elementary steps)
- exposure time: 100 seconds
- telemetry: 145 images of 1024 spectral x 120 spatial pixels (format 4)
- compression: quasilog-min-max (method 5)
- wavelength: 1526.70 Å on reference pixel 518 of Detector A
- rotation compensation: after complete scan, corresponding to
0.75 arcsec after 385.584 seconds
- binning: no spectral, no spatial
- on-board flat field correction: no
Remarks: The scan was performed in west-east direction, therefore the effective
field of view becomes approx. 191 arcsec. - The scan was started once before
(28.Oct.99, 23:23 UT), but interrupted in the middle.
