During Period 93, the ESO time slots are expected to be scheduled in late March, mid June and late July.
The exact distribution of the observing time between the APEX partners can be found on the APEX web pages. Time-critical observations should only be requested during the ESO runs.
Large Programmes with APEX using Poor PWV conditions: In order to make the best use of the time where the PWV is high (PWV>2 mm) ESO invites Large Programmes for those conditions. Poor PWV large programmes must be clearly identi ed as such in Box 5 of the large programme proposal form. Ideally a Poor PWV LP Programme" therefore consists of a large sample of targets covering a wide RA range. The proposal must demonstrate that the scienti c goals can be reached with only a signi cant subset of the observations completed. Poor PWV-LPs may cover up to 4 consecutive semesters.
In Period 93, SABOCA may only be available in June and July 2014. ESO may decide to execute accepted SABOCA programmes with Artemis instead if the first commissioning of the Artemis instrument shows a better performance at 350 m.
APEX-1: Large proposals for PWV>2mm conditions are encouraged.
APEX-T2 is o ffered conditional to a successful repair mission planned in January 2014. THz observations require excellent weather conditions (PWV<0.2 mm).
FLASH and CHAMP+: These PI instruments are o ered to the ESO community on a collaborative basis with MPIfR. Large programmes or time critical observations with PI instruments will not be accepted. Users who would like to use FLASH or CHAMP+ must contact the instrument PI, Dr. Rolf Guesten (rguesten[AT]mpifr-bonn.mpg.de), at least two weeks prior to submitting their proposal. Members of the PI team should be included as CoIs on the proposal. The operation of these PI instruments requires the presence of the instrument team so all ESO FLASH and CHAMP+ observations will be scheduled on fixed dates; the exact dates have not been determined yet.
FLASH observations will be done by the PI team during a maximum of 3 days. Preference will be given to proposals using the dual-beam, wide-bandwidth capabilities of FLASH due to limited ESO observing time.
Zspec: this broadband spectrograph is no longer offered at APEX.
