General Description

• This project aims at observing massive accretion disks in the CO fundamental
   band at 4.6mum. 2 sources have to be observed in two spectral setups to cover the
   whole fundamental band. To achieve the necessary S/N ratio two OBs have to be executed
   for SCI_IRAS18566-*, and only one for SCI_M8EIR. The SCI_M8EIR has a corresponding
   calibration OB as described in the SCI OB. For the 2 SCI_18566-* OBs, we request
   to execute the corresponding calibration OB (CAL_HR7557-1) inbetween the two science
   OBs. The choice of the calibration stars and times were directed to achieve at least
   the same S/N ratio or better than the corresponding science targets to assure that
   the calibration does not decrease the science S/N ratio.

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?

• YES

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?
