Slides and Notes 19-November-2010
Executive summary: There isn't a large vertical shift.
The SLM2/5 is the most nearly vertical, and in it we can look for deviations from
a fit to the "radial" CCDs. If one disk shifts, the fit adjusts but that disk
should still have the largest deviation.
| Station # | Name |
| 02 | ME+3 |
| 03 | ME+2 |
| 04 | ME+1 |
| 05 | MAB+3 |
| 06 | MAB+1 |
| 07 | MAB-1 |
| 08 | MAB-3 |
| 09 | ME-1 |
| 10 | ME-2 |
| 11 | ME-3 |
These numbers represent the shifts required to get the transfer
plates to line up in the local horizontal (tangent) and vertical (radial)
directions for each transfer line, where ME+4 and ME-4 are held fixed.
(Something has to be fixed--so these are relative displacements).
Some lines have poor profiles at critical locations, which means that
the distributions show a wide fuzziness, or even a bifurcation.
These correlate within a line: if a position lies within the faint blob at
point X, it will also lie within the faint blob at point Y.
The fits are plagued with bifurcations: instabilities in the fit
seem most likely. Instabilities in profile position for marginal
profiles are generally associated with large errors, which should reduce
the contribution.
The orientations should all be similar. Thus, if all lines
at one station show roughly the same "horizontal" shift, you may conclude
that that station has a rotation of (shift/7250) radians with respect to the
ME4 stations. If at a station
a line and its opposite number show "vertical" shifts of
the same size but opposite sign, that indicates a shift of that station.
In general, I would expect the station with the largest variation to
be the one in the line that moved.
For the SLM2/5 line, Transfer Line 2 has unfortunate fit instabilities, and something is causing
continuous shifts of the order of 50 microns. This is possibly ME-1, which shows the largest
swings. Something else drives a 100 micron shift in the ME1 starting in April, but it isn't
clear what. The largest changes are about 100 microns in April.
Transfer Line 5 shows an increase of 100 microns in ME+3/ME+2 (YE+2) in April and everything else is
fairly stable, albeit muddy. In short, looking at the most vertical CCDs, I see no evidence for more
than about 100 micron shift in disk positions.
| Transfer2Vertical02 | TL 2, ME+3 | 50 micron decrease from April to July, 20 micron swings: clear |
| Transfer5Vertical02 | TL 5, ME+3 | Bifurcates, one branch increases 100 microns in April |
| Transfer2Vertical03 | TL 2, ME+2 | bifurcation, 30 micron swings |
| Transfer5Vertical03 | TL 5, ME+2 | increases 100 microns in April |
| Transfer2Vertical04 | TL 2, ME+1 | bifurcation, 100 micron decrease from April to July, 50 micron swings |
| Transfer5Vertical04 | TL 5, ME+1 | stable |
| Transfer2Vertical05 | TL 2, MAB+3 | bifurcation, 50 micron swings |
| Transfer5Vertical05 | TL 5, MAB+3 | stable |
| Transfer2Vertical06 | TL 2, MAB+1 | bifurcation, muddy |
| Transfer5Vertical06 | TL 5, MAB+1 | stable |
| Transfer2Vertical07 | TL 2, MAB-3 | bifurcation, 25 micron swings |
| Transfer5Vertical07 | TL 5, MAB-3 | stable |
| Transfer2Vertical08 | TL 2, MAB-3 | bifurcation, muddy |
| Transfer5Vertical08 | TL 5, MAB-3 | stable |
| Transfer2Vertical09 | TL 2, ME-1 | trifurcation, 100 micron increase from April to July, large swings |
| Transfer5Vertical09 | TL 5, ME-1 | stable |
| Transfer2Vertical10 | TL 2, ME-2 | trifurcation, one branch shows 100 micron increase from April to July |
| Transfer5Vertical10 | TL 5, ME-2 | stable |
| Transfer2Vertical11 | TL 2, ME-3 | trifurcation, muddy, tight branch shows 50 micron decrease from April to July |
| Transfer5Vertical11 | TL 5, ME-3 | stable |
There are problems with Transfer Line 3 Horizontal Station 7 (300 micron excursion), with Transfer Line 6 Horizontal station 9
(400 micron excursion), and
with Transfer Line 4 Horizontal station 5 (1200 micron excursion).
