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.

Year IDL save file IDl variable name

1996 cat96.save.gz cat96

1997 cat97.save.gz cat97

1998 cat98.save.gz cat98

1999 cat99.save.gz cat99

2000 cat00.save.gz cat00

2001 cat01.save.gz cat01

2002 cat02.save.gz cat02

2003 cat03.save.gz cat03

2004 cat04.save.gz cat04

2005 cat05.save.gz cat05

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')

or through:

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.
