Method: use SOHO/EIT as base to line everything up on, i.e., get shifts relative to these instruments. By comparing lines formed at the same or similar temperatures, we get relative shifts which can be followed back to the reference instruments (marked Result below).
Note, shifts are already included in images linked below. Also, first instrument in title is the base, second (and third) overlaid in contours. Shifts are in arcseconds. You can check out (or run) the program that does the shifts. You will also need the datafile of idl maps of each instrument's observations.
These overlays are primarily for lining up purposes. Further
overlays are also available.
1) line up TRACE 195 Angstroms with EIT 195 Angstroms
Same line line-up and Result: TRACE needs to be shifted [0,-7] w.r.t. EIT2) line up TRACE 171 Angstroms with CDS Mg10
Similar temperature line-up: CDS needs to be shifted [-4,11] w.r.t. TRACE3) line up EIT 195 Angstroms with CDS Mg 10
Result: From 1) and 2), CDS needs to be shifted a total of [-4,4] w.r.t. EIT4) line up CDS Si12 and SXT AlMg
Fairly similar temperature line-up: SXT needed to be shifted [5,-8] w.r.t. CDS.5) line up EIT 195 Angstroms with SXT Al Mg
Result: From 4) and 3) SXT needs to be shifted [1,-4] w.r.t. EIT6) line up BBSO H-alpha and EIT 304
Similar temperature line-up and Result: BBSO needed to be shifted [-1,10] w.r.t. EIT7) line up BBSO H-alpha with PICS H-alpha
Same line line-up: PICS needed to be shifted [5,-16] w.r.t. BBSO, so Result from 6) and 7): PICS needs to be shifted [4,-6] w.r.t. EIT8) line up CHIP He 10830 with PICS H-alpha
Fairly similar temperature, more importantly similar time line-up: CHIP needed to be shifted [-5,5] w.r.t. PICS9) line up CHIP He 10830 with EIT 195 Angstroms
Result from 8) and 7): CHIP needs to be shifted [-1,-1] w.r.t. EIT10) line up CHIP He 10830 with CDS He1
Similar temperature line-up: from 9) and 3) CHIP needed to be shifted [3,-5] w.r.t. CDS11) line up MDI and BBSO H-alpha
Assuming MDI and EIT are co-aligned, BBSO is also shifted [-1,10] w.r.t. MDI12) Also show BBSO H-alpha overlaid by MDI
13) line up PICS H-alpha and MDI
Assuming MDI and EIT are co-aligned, PICS is also shifted [4,-6] w.r.t. MDI12) Also show MDI overlaid by PICS H-alpha
