!eis_vso_day
To get all of the EIS files for a specific day from the VSO, you can do:
{{eis_vso_day,'16-feb-2011'}}
This will download the files to a temporary directory and then ingest them into the EIS file hierarchy using the routine eis_ingest. If you're not sure where the files will be downloaded to, then give the keyword /test. For information on how to organize your EIS data, please check [EIS Software Note No. 18|http://solarb.mssl.ucl.ac.uk/SolarB/eis_docs/eis_notes/18_FILES/eis_swnote_18.pdf].
!eis_vso_download_files
Another way of accessing the VSO is with this routine. It is most useful when used in conjunction with eis_obs_structure. The example below shows how every raster with the name 'Atlas_30' can be downloaded:
{{s=eis_obs_structure(rast_acr='Atlas_30') \\ eis_vso_download_files,s}}
As with eis_vso_day, the files will automatically be downloaded into the EIS file hierarchy.
The second example shows how all narrow slit rasters containing the Fe VIII 185.21 line during the period 1-Jan-2015 to 1-Mar-2015 can be downloaded:
{{s=eis_obs_structure('1-jan-2015','1-mar-2015') \\ s2=eis_filter_obs_stric(s,wvl=185.21,/narrow) \\ eis_vso_download_files,s2}}
For more details on these routines, please check out [EIS Software Note No. 25.|https://sohoftp.nascom.nasa.gov/solarsoft/hinode/eis/doc/eis_notes/25_IDL_SEARCH/eis_swnote_25.pdf].
