SUMER study #2113: He II (1085), N II raster scan at coronal hole
- date, time: 19.Oct.99, 15:00 - 21:03 UT
- field of view: 439 - 277 arcsec E, 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: 145 images of 512 spectral x 360 spatial pixels (format 38)
- compression: quasilog-min-max (method 5)
- wavelength: 1080.00 Å on reference pixel 512 of Detector A
- rotation compensation: after complete scan, corresponding to
0.75 arcsec after 310.719 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. 215 arcsec.
