This is the start page for a collection of SUMER scans that will eventually
form the basis of the SUMER Atlas book project. The collection is seperated
into months.
Scans were performed between January and October 1996, and between February
and November 1999. Scans by solar rotation (performed in "sit-and-stare" mode)
may be included later.
The scan collection is automatically produced using the SUMER image database
in Lindau, i.e. the contents of the SUMER image headers. This approach is still
new and not fully debugged. Sets of image data are considered "scans" if they
have
(a) a field-of-view larger or equal to 50 arcsec, (b) an absolute raster step
size larger than 0 arcsec, (c) an abolute raster step size less or equal 9
arcsec (but probably only step sizes below 4.5 arcsec will be considered in
the end).
Each list entry consists of one scan (or several repetitions of one scan) in one
spectral window and can contain several lines (ions) and/or continuum. If scan
images have been processed they appear as links to .GIF files at the right end
of the entry. (Oversized images covering a whole solar diameter are split in
their east and west half.) In this way, the collection will slowly grow
towards completion in the future.
The list entries contain the following information:
- da: day of month
- first: start time of first exposure, in hh:mm UT
- last: start time of last exposure, in hh:mm UT
- archive: study number in SOHO archive, the last two digits
denote a running number of studies starting this day, the (up to) four first
digits denote the day of mission; additional information about the studies
(e.g. target, title,...) can be included using this key and the monthly study
database
- im: SUMER image format number
- d: detector A or B
- s: SUMER slit number 1,...,8
- xmin: minimum commanded E-W-coordinate of field-of-view
(E = negative, W = positive), in truncated arcsec from solar center
- xmax: maximum commanded E-W-coordinate of field-of-view
(E = negative, W = positive), in truncated arcsec from solar center
- y-coo: commanded S-N-coordinate (S = negative, N = positive) of
slit center, in truncated arcsec from solar center
- expos: exposure time in truncated seconds
- wavelng: commanded wavelength in Å
- rpix: reference pixel, position of commanded wavelength on detector
- st: raster step size in elementary units of 0.375 arcsec
(normal step mode = positive, "Schmierschritt" = negative)
- r: rotation compensation (negative value [off] = -, standard =
0, positive value [user selected] = +)
- rast: commanded number of raster movements, usually one less than
total number of images (W-E-direction = negative, E-W-direction = positive)
- totl: total number of slit images in a raster or series of
rasters (has to be multiplied by three for image format 45)
