Estimated Total Execution Time (hours, including overheads)

• 3.5h

General Description

• Continuous observations of the High Amplitude delta Scuti star 1 Mon are
   required. The star pulsates with a main period of 3.27 hours so these observations
   should cover one complete cycle. Four OBs are submitted to secure the data. These
   OBs add up to a total time of 03:24:00h although skipping of acquisition in OBs
   2 to 4 should shorten the execution time. The verification of the wavelenght settings
   will be achieved by observations of arcs in the first 3 changes in the first two
   OBs and for each setting change in the last two OBs. A cool telluric standard will
   be needed and could be observed at the beginning or at the end of the observations
   to not to interrupt the sequence. Ideally the telluric standard would be that which
   also is a radial velocity standard. A final OB "1Mon_Hband-5" is submitted in case
   rounding up of the observing time with the awarded time is needed.

Waiver Requests

• No Waiver Request was submitted

Critical Observing Condition Constraints

• No critical observing conditions required

Time-Critical Aspects

• The star will be visible above airmass 2.2 only for the 3.5h of time awarded
   if observations are taken from the very beginning of the night. The 3.5h have to
   be taken continuously in a single night. The night astronomer have the flexibility
   of skipping all further acquisitions after the first OB if one at the beginning
   was sufficient. OBs should be executed in the order provided by the names, i.e.,
   1,2,3,4 and 5. Do OB "1Mon_Hband-5" to fill the observing time awarded if needed.

Special Execution Requirements

• Continuous observations will be needed from the beginning of the night
   with a duration of 3.5h. To do so, 4 OBs have been submitted with a duration of
   1:01:21 hours the first two and 00:40:39 the last two. A fifth OB has been submitted
   to fill in any remaining time of the 3.5 h of observing time awarded.

Special Calibration Information

• A cool (G spectral type) telluric standard will be needed and could be
   observed at the beginning (even in twilight time if needed) or at the end of the
   observations to not to interrupt the sequence. Ideally the telluric standard would
   be that one which also is a radial velocity standard. A S/N ratio of greater than
   100 is required for the standard in the wavelength ranges observed for the target,
   viz. 34/-1/n, 33/-1/n and 33/1/n.

ToO Activators List

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?

• YES

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
