NOTES FOR TARGET FIELDS
-----------------------------------------------------------------------

Our program is to observe bright Kuiper Belt objects (KBOs) to 0.01
arcsecond precision in order to obtain very precise astrometry.

Some objects can only be observed at the very beginning or end of the
night.

The observations are simple direct imaging in the R-band.  Images of
the KBOs should be no more than about 10 minutes each to prevent
trailing losses of the moving KBOs.

15 arcsecond dithering between successive images is requested.


-----------------------------------------------------------------------
NOTES FOR CALIBRATION FIELDS
-----------------------------------------------------------------------

No standards are needed.

Only flats and biases are needed in the R-band.

Epoch is J2000

Please image all objects listed for the required time.

No finder charts.
Airmass less than 2.0 preferred if possible.
R-band filter for all observations.
All integrations 600 seconds.
Please dither about 15 arcseconds between images.

The proper RA and Dec for each KBO for late January 2009 is put  
below.  Please
observe the object for the full amount of time as stated.
