This section describes relevant changes for observations to take place during Period 95.

General

• During Period 95, the ESO time slots are expected to be scheduled in late April and late June.
  
• 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 and 8 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.

Instruments

• The new 350 μm camera ARTEMIS is offered conditional to its successful commissioning in June 2015. ARTEMIS will cover a field of view of 4'x2'. Parallel observations at 450 μm may be available, but cannot be guaranteed. Sensitivity estimations for 450 μm will not be available before the deadline, and the science case should not depend on this band. If the commissioning is delayed, ESO may execute ARTEMIS programmes with SABOCA instead. A new observing time calculator is available
  
• SABOCA  is not offered in Period 95 as the same capabilities are offered by ARTEMIS.
• SHFI:
  • APEX-1: Large proposals for PWV>2mm conditions are encouraged.
  • APEX-T2 is offered conditional to a successful repair mission planned in June 2014. THz observations require excellent weather conditions (PWV<0.2 mm).
• FLASH and CHAMP+: These PI instruments are offered 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.
• SUPERCAM: This instrument is offered conditional to a succesful commissionin in November 2014, and will only be available in late April. For operational reasons, only observations of CO(3-2) at 345 GHz will be accepted. Users of this new PI instrument are encouraged to collaborate with the instrument team (PI Chris Walker iras16293 [AT] gmail.com). For observing time calculations, users should use the SHFI/APEX-2 On-The-Fly calculator, but divide the total time request by 16. This factor takes into account both the 64 pixels and the higher receiver temperature of the SUPERCAM receivers compared with SHFI.
