!!!Downloading EIS data through the IDL command line

Sometimes it can be convenient to download directly from the IDL command line, and two options are available.


!!VSO

To search for and download EIS data for a specific date range, the following commands are used:

{{list=vso_search('16-feb-2011 06:15','16-feb-2011 12:30',inst='eis')\\
chck=vso_get(list)
}}

There are 64 FITS files corresponding to this time range and they will be downloaed to your current working directory.

!!Oslo Data Center

The Oslo data center can also be accessed from IDL and the same search described above is performed as follows:

{{o=obj_new('osdc')\\
o->condition,'INSTRUME: ,EIS'\\
o->condition,'EPOCH_START: 16-feb-2011 06:15'\\
o->condition,'EPOCH_END: 16-feb-2011 12:30'\\
o->search,out\\
paths =  o->paths(out,/fetch)
}}

One difference compared to the VSO is that the Oslo software makes use of the $HINODE_DATA environment variable (see [EIS Software Note No. 18|ftp://sohoftp.nascom.nasa.gov/solarsoft/hinode/eis/doc/eis_notes/18_FILES/eis_swnote_18.pdf]) to download the files into the correct level-0 directory.

Note that, if you perform a search using the web-based search tool at Oslo, at the bottom of the results page will be written the IDL commands that would have yielded the same search results.
