Making use of AIA data for EIS analysis#

(This is work in progress...)

Obtaining AIA cutout images#

The request for AIA cutout images can be made directly made from IDL as seen from the example below:

IDL> ssw_cutout_service,'8-feb-2011 18:38','8-feb-2011 19:50',cgiquery,queryout,ref_helio='S30E36',ref_time='8-feb-2011 18:38',fovx=100,fovy=100,wave='193',email=email_address,max_frames=73

This requests 1 min cadence 193 A images for the time period 18:38-19:50 on 8-Feb-2011. The FOV is 100" x 100" and the center of the FOV is given by ref_helio in longitude-latitude coordinates. The reference time at which the pointing coordinates are specified is given by ref_time. It's important to give an e-mail address so that you receive notification when the cutouts are ready.

If your coordinates are in heliocentric units, then you can convert them to longitude-latitude by

IDL> lonlat=xy2lonlat((x,y),ref_time)
