The data archive
For users who do not hold the CDS data archive is it possible to search through an IDL variable which contains the fits headers to find data which can then be requested.
Right click on the relevant save file. These files are around 1Mb in size.
The above save files have been created through the IDL procedure headcat. For example:
IDL> headcat, cat96, year=1996
They can be gunzipped and then restored into an IDL session via:
IDL> restore, filename='cat96.save'
For information on the tags within the structure type:
IDL> help, cat96, /str
To find out the science target of each observation print or search through cat96.SCI_OBJ. For example:
IDL> ss = where (cat96.SCI_OBJ eq 'Synoptic Meridian Images')
IDL> print, cat96(0).object
The CDS study title can be found via
IDL> print, cat96.SCI_SPEC
Once you have found in the catalog some data that you would like to obtain, go to
the Solar UK Research Facility to request them.
