General Description

The idea behind this programme is obtaining a radial velocity curve for
 HD 306414, a B1Ia supergiant orbited by an X-ray pulsar. To this purpose, we would
 like to obtain spectra of the source at random phases in the 330 day cycle. We include
 OBs for another star of similar spectral type (to be cross-correlated against) and
 a bright radial velocity standard.

Critical Observing Condition Constraints

The orbit is very long. So taking more than one observation per night
 does not make any sense. As a matter of fact, it would be convinient to leave at
 least one week between two consecutive observations. Close to periastron, i.e.,
 during January and February, the span between two consecutive observations may be
 dropped to 2 or 3 days.

Time-Critical Aspects

X-ray maximum happens in early February. Observations around this epoch
 would be of higher value than at other epochs.

Special Execution Requirements

Special Calibration Information

A wavelength lamp is included in each OB. We include an OB for a radial
 velocity standard, but this is not fundamental for our programme.

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 ?

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 ?

```
N/A
```

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

```
N/A
```

Did you set 'New Preset' flag in all acquisition templates to 'True'?

If you use any lamp, did you check that it should never be left on at the end of any OB?
