SUMER study #2116: Coronal hole scan around 1032 Å
- date, time: 19.Oct.99, 21:13 - 20.Oct.99, 01:15 UT
- field of view: 542 - 380 arcsec E, 164 - 284 arcsec N
- slit: 0.3 arcsec x 120 arcsec, centered (number 7)
- 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: 1032.000 Å on reference pixel 812 of Detector A
- rotation compensation: after complete scan, corresponding to
0.75 arcsec after 339.793 seconds
- binning: no spectral, no spatial
- on-board flat field correction: no
Remarks: The scan was performed in east-west direction. Therefore, considering
the Solar rotation, it covers less space (130 arcsec) than the nominal pointing
indicates.
