General Description

IPOL program of moving targets with R Bessel filter. For each target,
 the OBs (imaging linear polarization) should be executed at different phase angles,
 as specified in Section "Time-critical aspects". Each OB consists of acquisition
 plus 8 exposures with the lambda/2 retarder waveplate at 0, 22.5, 45, 67.5, 90,
 112.5, 135, 157.5 deg, respectively. Six out of our 15 OBs have execution time longer
 than 1h (for Huya and Varuna). OB execution cannot be splitted. Target coordinates,
 as well as additional velocity, must be entered according to the ephemeris files
 (see Section "Time-Critical aspects").

Waiver Requests

Request to exceed execution time longer than 1h approved by waiver 178.C-0036F.02

Critical Observing Condition Constraints

```
None
```

Time-Critical Aspects

Each OB should be executed in the time intervals specified below. These
 intervals have been selected according these criteria:

1) to satisfy the observing constraints (visibility and and lunar illumination);
2) to cover adequate target phase coverage
3) to avoid background crowdness (i.e., we have avoided those observing when our
 targets are too close to brighter objects). 

TIME CONSTRAINTS AS ARE REFLECTED IN THE OB NAMES (and refer to UT!!!) 
We are aware that time constraints will be respected on a best efford basis. However,
 time constraints on Chiron observations are of crucial importance. If Chiron observations
 cannot be executed in August, they will have to be re-scheduled in another period.
 We will monitor the program execution and inform USD accordingly.

Special Execution Requirements

Target coordinates and additional tracking velocity must be typed in prior
 OB execution based on the ephemeris provided as function of UT with the OB.

OB execution cannot be splitted in two or more parts: if OB is interrupted for any
 reason, observations must be resumed immediately, otherwsie the entire OB has to
 be classified "C", and its execution repeated. In other words: one cannot execute
 half of the OB onenight, and the remaining half another night.

Please have a look at the photon counts and check carefully for saturation (the
 magnitude of our targets may be slightly different than expected)
