Estimated Total Execution Time (hours, including overheads)

• 25 x 25:38 min = 10.7 hrs

General Description

• K band (2329.3nm) spectra of TW Hya to measure RV. Spectral calibration
   will be done with telluric lines. No standard star observation for calibration required.
   Total execution time of one OB is 25:38 min (ETC). We need 25 such observations
   of TW Hya, spread as evenly as possible over at 10-15 (possibly consecutive) nights
   (see time-critical aspects). There are 25 identical OB available for 25 identical
   observations.

Waiver Requests

• No Waiver Request was submitted

Critical Observing Condition Constraints

• None.
  Clear sky, seeing better 1.4 arcsec, airmass <1.5, moon phase not relevant.

Time-Critical Aspects

• The 25 observations of TW Hya shall be spread as evenly as possible over
   at least 10 (10-15) nights, which should be consecutive, if possible. Note that
   the period of the expected RV variation, which we want to cover as good as possible,
   is 3.56 days. Due to the day/night intervals, this cannot be done in less than 7
   nights. Ideally, the two observations per night should separated by 4-5 hrs.

ToO Activators List

• N/A

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?

• N/A

Do any OBs include wavelength or flatfield calibrations?

• NO

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?
