Estimated Total Execution Time (hours, including overheads)
General Description
This is one of three runs with spectroscopy of a peculiar star V838 Mon.
One of the aims of the whole project is to investigate spectral time variability
of the taget on time scales of weeks.
A single run is composed of three OBs, i.e. two scientific exposures and one flux
calibration observation. They all have the same spectrograph standard setting RedArm580
with IS#1 and slitwidth 0.8 arcsec.
Waiver Requests
Critical Observing Condition Constraints
Time-Critical Aspects
These OBs are requested to be executed between:
run C: 2009.03.20 - 2009.04.10
The OB named CAL_HILT600_C is an observation of a spectrophotometric standard and
should be obtained directly after V838MON_RED580_C_EXP2. These two OBs have total
execution time of 1.0 h.
The OBs: V838_RED580_C_EXP1 and (V838MON_RED580_C_EXP2 + CAL_HILT600_C), can be
executed in any order. We are going to average the spectra of V838 Mon from the
two OBs. We expect the target to be variable on time scales of weeks, so we request
for obtaining all the OBs within time span not longer than 5-6 days. The shorter
the time span between execution of V838_RED580_C_EXP1 and (V838MON_RED580_C_EXP2
+ CAL_HILT600_C), the better for the project. The most preffered situation is obtaining
them on consecutive nights.
Special Execution Requirements
The OBs: V838_RED580_C_EXP1 and (V838MON_RED580_C_EXP2 + CAL_HILT600_C),
can be executed in any order. We are going to average the spectra of V838 Mon from
the two OBs. We expect the target to be variable on time scales of weeks, so we
request for obtaining all the OBs within time span not longer than 5-6 days. The
shorter the time span between execution of V838_RED580_C_EXP1 and (V838MON_RED580_C_EXP2
+ CAL_HILT600_C), the better for the project. The most preffered situation is obtaining
them on consecutive nights.
Special Calibration Information
The OB CAL_HILT600_C is a flux-calibration observation that should be
executed directly after V838MON_RED580_C_EXP2, i.e. when the standard star has a
similar airmass as the scientific target.
The observation of a spectrophotometric standard is crucial for our project, since
we are going to perform detailed analysis of fluxes in forbidden emission lines.
The spectrophtometric standard star Hiltner 600 (HLTR600) is one of the UVES standards
(sp. type B1, V=10.44 mag).

Do all your OBs comply with the instrument-specific requirements listed
on the instrument-specific Phase 2 web page ?
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 specified the S/N ratio at given wavelength in the User Comments
field of each OB?
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 ?
If you need secondary guiding, are there suitable objects within 30 arcsec
from your target ?
