Style of Access
There are four ways to access the SuperCOSMOS Galactic Plane data
which are described below.
- GENERAL IMAGE/CATALOGUE EXTRACTION.
Download a specified
Galactic Plane region up to 30 arcmins across returning both
the pixel image and associated object catalogue for the selected region.
Note that by default only the H-alpha data are returned
but the user may select either H-alpha/SR or both survey bands if desired.
The object catalogue is selected on the fly from a larger database
including any detections at the other wavebands currently available
(e.g. H-alpha or SR2 and later I and SR1). Note that the IAM
parameters in the object catalogue come from an Image
analysis of the base SuperCOSMOS pixel data where the pixel data has
not been Flat-Field corrected.
If you select the H-alpha survey, your catalogue will have everything
seen on the H-alpha exposure together with
all the other available magnitudes (SR2, I, SR1) and a selection of
associated IAM parameters, all retured in matched blocks of four
columns for each parameter.
- LARGE CATALOGUE. Download object
catalogue from a large area
(up to 10 degrees across). Again, this is created on the fly from a larger
database, taking one particular Plane survey as the base-survey. You
can control the list of parameters returned.
- BATCH MODE. You can specify a
disjoint list of regions (coordinates) to extract. Tar savesets of the images
and associated catalogues are returned.
- ALL GALACTIC PLANE SEARCHES / ANALYSIS. It is not currently
possible to download the
whole database. However searches through the entire survey material can be
done (e.g. "find all the objects brighter than X") by arrangement with
the WFAU on our own machines - contact Mike
Read (email@example.com) to discuss the possibilities. Later we hope to provide
this as an automatic service.
