DEFAULT OPTION - Quiet Sun (QS):

- target: disk center for all instruments
- TRACE : 160nm channel

OTHER OPTION - Active region (AR):

- target: active region or its renmants near the disk center
- TRACE : 19.5nm channel

COMMON THINGS:

- all other instruments have the same observing procedure for both 
  QS and AR measurements

- PREFERRED OBSERVING TIME SLOT: 

  CDS_MDI+EIT/SOHO, TRACE, SOT+XRT/Hinode: 07:00 - 13:30
  EIS/Hinode: ~09 - ~13 UT
				 	     
- ROTATION COMPENSATION:

  SOHO   : none (also CDS)
  Hinode : yes (all instruments) 
  	   if disk center observed then to have x~=0 at 10UT  	    	      	
  DOT    : yes 
	   if disk center observed then to have x~=0 at 10UT
