SUMER study #687: Disk center scans in O IV
- date, time: 16.Sep.96, 03:35 - 04:01 UT, 05:04 - 05:29 UT
- field of view: 56 arcsec E - 56 arcsec W, 150 arcsec S - 150 arcsec N
- slit: 1.0 arcsec x 300 arcsec (number 2)
- raster step size: 0.75 arcsec (2 elementary steps, oversampling)
- exposure time: 10 seconds
- telemetry: 2(scans)*151 images of 25 spectral x 360 spatial pixels
(format 12)
- compression: quasilog-min-max (method 5)
- wavelength: 1401.20 Å on reference pixel 621 of Detector A
- rotation compensation: 0.75 arcsec after 286.303 seconds
- binning: 2 spectral pixels, no spatial
- on-board flat field correction: no
Remark: The field of view was scanned twice, before and after studying the
monochromatic line ration O IV (1399/1401) for one hour.
