General Description

These OBs are used to measure the radius of R Cet in different wavelength
 bands. OBs 0 to 5 are scheduled before max light, when there is not yet line doubling
 
confusing the radius measurement. This is the reason for the time constraint. These
 OBs should preferably be scheduled within a few nights, so that the radii in the
different lines may be inter-compared. OBs numbered 6 to 11 are scheduled around
 mininum light, for comparison.

Time-Critical Aspects

OBs 0 to 5 are scheduled within Dec 15 2009, - Jan 15 2010, i.e., before
 max light, when there is not yet line doubling 
confusing the radius measurement. This is the reason for the time constraint. These
 OBs should preferably be scheduled within a few nights, so that the radii in the
different lines may be inter-compared. OBs numbered 6 to 11 are scheduled during
 october, before mininum light, for comparison.

R Ceti (P = 166 d) Max light: Aug 29, 2009; Feb 10, 2010  - Min light : Dec 1 ,
 2009

Special Execution Requirements

OBs 0 to 5   scheduled as closely together as possible. Same for OBs 6
 to 11

Do all your OBs comply with the instrument-specific requirements listed on the instrument-specific Phase 2 web page ?

If this is a pre-imaging run, did you select PRE-IMAGING for the Observing Category for each Observing Template ?

```
N/A
```

Do all your finding charts comply with both the general and instrument-specific Phase 2 Web Pages ?

If you submitted OBs for standard stars, did you specify the magnitude and spectral type of all standard stars in the OBs ?

Have you included OBs for any calibrations that you need but which are not part of the Calibration Plan ?

```
N/A
```

If you are observing Moving Targets, have you attached suitable ephemeris files to your OBs?

```
N/A
```

If you have preferences which OBs should be executed first, did you make use of the User Priority field in the OBs ?

If this is a run that requires coordinated observations with other facilities, did you give proper instructions in the Time-Critical Aspects Section ?

Did you indicate for each science star OB the corresponding calibrator star OB (and vice versa) in the 'Instrument Comments' field ?

Did you check that your chosen calibrator is bright enough for the instrument mode used ?

If you use calibrator stars which are not in the CalVin database, did you specify their characteristics in the README file and in the OBs ?

```
N/A
```

Do you use the same DIT for pairs of science target and associated calibrator?

Are the magnitudes of science target and calibrator within +/- 1 mag ?

Did you verify that your coordinates are as accurate as possible (2Mass coordinates recommended) and that they include proper motions if available ?

Did you specify the LST range of the calibrators such that they cover the range from 30 min before the start of the LST range of the science target to 30 min after the end of the LST range of the science target ?
