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.

We will also observe some field stars to determine their 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.  Field star images are 60 or 80
seconds each.

15 arcsecond dithering between successive images is requested.

All objects should be observed on both nights.  If time is short or
weather is bad please observe only the high priority targets.


-----------------------------------------------------------------------
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 on both nights.
If extra time is available repeat objects but only after all objects
have been observed at least once in good conditions.

No finder charts.
Airmass less than 1.5 preferred if possible.
R-band filter for all observations.
All Kuiper Belt Object integrations 600 seconds.
Field star integrations are 60 or 80 seconds.
Please dither about 15 arcseconds between images.

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