Estimated Total Execution Time (hours, including overheads)
General Description
These observations are made with AMBER using UT1-UT2-UT4 in low resolution
mode. Note that UT1-UT3-UT4 can be also used if needed.
It consists in a serie of 3 calibrated observations. Ultimately, each of the three
points should be separared by 1.5h such as h=-1.5,0,1.5 (with one point at h=0).
It can be more if it is technically possible. e.g. two hours between each calibrated
point like h=-2,0,2 for example. It cannot be more considering the LST interval
time available with respect to starset and delay lines limit.

Critical Observing Condition Constraints
Time-Critical Aspects
Teh observations must be performed before the beginning of June. From
June, this star is not observable during night time, or at very low elevations only.
Beginning of March to end of April is the best suited period.
Special Execution Requirements
Since a calibrated point consist in one CAL + one SCI observation, a procedure
such as:
CAL (h1)-SCI (h1)/CAL (h2)-SCI (h2)/CAL (h3)-SCI (h3) (h1, h2, h3 beeing the 3 hour
angles)
seems suited. SCI (h1)-CAL (h1)/SCI (h2)-CAL (h2)/SCI (h3)-CAL (h3) is an alternative.
Nota: If observations are fast enough too do 3 observations in the official 70min,
bracketting the SCI target by CAL observations (CAL/SCI/CAL) would be of course
perfect.
If for the integration time of 25ms, the flux is low (but fringes are there), it
can be increased, e.g. to 50ms.
Special Calibration Information
the calibrator is HD101917, K0III star. K=4.3, H=4.2.
11 42 54.933 -79 18 23.00
If for any reasons, this calibrator is not working, there is an alternative one
slightly brighter proposed in the OBs:
HD106248, K2.5III star. K=3.7, H=3.8.
12 13 56.463 -78 34 26.16

Is this a Pre-imaging run ?
Pre-imaging Requirements
Source(s) of Pre-imaging
Pre-imaging sources not listed above
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 ?
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?
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 ?
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 ?
