Demo

Search A: Find all EIS limb observations of the poles (or to be precise: find all EIS level 0 files with radial coordinate at centre of the FOV greater than +900” and x coordinate of the centre of the FOV between -50” and +50”.)

Search B: Find observations from all instruments taken the 10th october 2007 between 06:00 - 07:00 UT (the search criteria were simply fine tuned in order to find a small collection of observations from all instruments.)

In my presentation at the workshop I demonstrated searches that were saved in my web browser using the archive’s built in “Save current criteria” functionality. In order for you to see these searches they are

provided as hyperlinks below. I’ve also added a step-by-step walkthrough of my demo of Search B on the next slide, and as an extra bonus I’ve even added some additional information. Enjoy!

EXTRA

Walkthrough of demo: perform Search B, then:

1. Sorting I: Sort the files in order of increasing x coordinate of the FOV (click the word xcen on top of the xcen column)

2. Sorting II: Sort in alphabetical order of the instrument name (instrume)

3. Removing unwanted files: Remove EIS and XRT files by clicking the grab from here and down symbol ( ) on the first line of SOT files, then grab from here and up ( ) on the last of the SOT lines.

4. See all files in a file group: Click the expand group symbol ( ) on the first line in order to see all the 23 files in this group.

5. Download files: A single file may be downloaded by clicking . Several files (or groups of files) are downloaded by checking the checkboxes of the files (or groups) you want, then pressing the . button. Get all files on the current search result page by simply pressing .

6. See header information: See file information by clicking , click to see full FITS header.

Additional information

Colour coding: when you tab or click out of a search field, it will change colour after a couple of seconds. This is because the search is actually already done, and the colour tells you the result of the search:

1. Green fields: there are files matching all search criteria (the number of files/groups that were found is printed right below the SDC logo banner)

2. Yellow fields: no files found matching all of the yellow fields simultaneously (here: all files older than 1. oct 2007 are level 0 files, all quicklook files are newer than this date)

3. Pink fields: no files matching any of the pink fields (here: there are no files older than 1. oct 1999!)

4. Red fields: malformed.

Additional information

Saving of searches: you may save your favourite searches in the following way:

1. Cookies: After you have filled in your search criteria, write a name for the search in the “Save current criteria as” text box at the bottom of the page, and press return.

2. Bookmarks: Fill in search criteria, click , and bookmark the search result page. If you want to share your search with a colleague, you may e-mail this URL to him/her.
