Estimated Total Execution Time (hours, including overheads)

• 11.93

General Description

• The goal of the observation is two folds: 1) to obtain the spectra of
   CO fundamental band at 4.6um (for low rotational J state) and 4.9um (for high rotational
   J state), and 2) and to do so in spectroastrometric manner. the diffraction limited
   spatial resolution is critical. We exceed the officially allocated time (11.5 hours)
   by 26 minutes (3.7%). This is because we have to split the calibration OB into two
   for three objects so that each single object OB has its own calibratin OB, although
   these two calibration OBs are short enough to be executed in an hour together. It
   penalized us three more acquisiions for the calibaraion, and thus the exceed of
   the observing time. 
  We appreciate your understanding.

Waiver Requests

• No Waiver Request was submitted

Critical Observing Condition Constraints

• not critical, but we hope that the OB will be executed under the average
   humidity condition or better, because the water absorption that fall in the relevant
   wavelengths is hard to remove.

Time-Critical Aspects

• We hope the observation of the spectroscopic standard star will be executed
   within 2 to 3 hours before or after the corresponding object OBs are executed. Matsching
   of the airmass should be also taken into account.

Special Execution Requirements

• We hope the observation of the spectroscopic standard stars will be executed
   within 2 to 3 hours before or after the corresponding object OBs are executed. Matsching
   of the airmass should be also taken into account.

Special Calibration Information

• We have found that the final S/N is often limited by the S/N of the standard
   star in many archival data. this is because the objects in this kind of projects
   are often one of the most bright infrared sources on the sky. casual selection of
   standard star damages the final quality of the data critically. the present standard
   star HR 2294 is selected so that it matches in the middle of the RAs of the objects,
   and bright enough so that the s/n of the standard star does not limit the quality
   of the final data even for the brightest target of our list. however, for any reasons,
   the change of the standard star is preferred, we would like to be consulted before
   the observation. the backup atmospheric calibration stars in the case that HR2294
   is far mismatch with the object airmass is 
  
  HR 2004 05:47:45.4 -09:40:11 (J2000) V=2.06, B0.5Ia, K=2.68, M=3.18
  HR 2618 06:58:37.5 -28:58:20 (J2000) V=1.50, B2II,  |K=2.22, M=2.72
  
  only in the case the mistach of the airmass all above three is larger than 0.15,
   please go with a different spectroscopic standard. 
  we would like the alternative spectroscopic standard to be very bright (M<3),
   with the spectral type earlier than A3, with preferable luminosity class brighter
   than a giant (

Do the README file and the instrument comments of the telluric stars
 OBs include the required S/N/pixel of the spectrum of the telluric star, its spectral
 type and allowed spectral range?

• YES

Do any OBs include wavelength or flatfield calibrations?

• N/A

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

• N/A

If the slit viewer guide star is different from the target, are the RA
 and DEC offsets accurate to within 0.05 arcsec and do they take into account the
 relative proper motion between the two objects?

• N/A

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

• YES
