General Description
MIDI GTO observations of bright AGB stars. Targets are typically brighter
than calibrators, but more resolved. The program is aimed at monitoring a number
of cool stars. We anticipate that some of the observations cannot be carried out
within the time constraints - this should not have any influence on the others.
/ About the variability of the calibrator stars (HIP, Combined General Catalogue
of Variable Stars): 30 Psc = Vmag variable with an amplitude between 0.06-0.6 mag
/ Alpha Hya = Vmag variable with an amplitude < 0.06 mag / About the variability
of the target stars (AAVSO): V Hya = has two periods: [1:] 18 month with variability
in V with V between 6.5 - 9.5 mag (next MAXIMUM in February 2010); [2:] 17 years
with a 2-3 years minimum light phase with 13 mag in V (next minimum light phase
will be 2010-2013), the V mag between these minima is given by [1] / R Hya = variability
in V with V between 4 - 10 mag, period: 11 month (next MINUMUM in Nov/Dec 2009)
/ W Hya = variability in V with V between 6 - 9 mag, period: 12 month (next MAXIMUM
in December 2009) / R Aql = variability in V with V between 6 - 11 mag, period:
9 month (next MINUMUM in Februar 2010) / R Aqr = variability in V with V between
6 - 11 mag, period: 12 month (next MAXIMUM in January 2010) / All stars almost not
variable in N-band / Please take aquisition images.

Critical Observing Condition Constraints
Time-Critical Aspects
Two epochs are foreseen for V Hya. The exact date of the observations
is not critical, but OBs SCI_VHya_3, _4, and _5 should be executed at least one
month after OBs SCI_VHya_1 and _2.

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 ?
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 ?
