-Proposers are free to adjust the length of the various proposal sections within this overall length limit.The strongly recommended breakdown is 2 pages for the Science & technical justification and 2 pages for Figures, tables and references. Figures and tables may be interleaved in the text, so that e.g. figures appear close to the location where references are made to them. Where relevant, a brief summary of any related EVN proposals already observed or scheduled should be included in the justification. Proposers should indicate if it is a resubmission of an earlier proposal. +Proposals should have ​__up to 2 pages of text for the Science & Technical justification__ and 2 pages for figures, tables and references.​ Figures and tables may be interleaved with the science and technical justification, so that e.g. figures appear close to the location in the text where references are made to them.

 ===== Targets of Opportunity (ToO) ===== ===== Targets of Opportunity (ToO) =====
  
-Targets of opportunity (ToO) are defined to be extremely rare and/or unpredictable events where there is a limited opportunity to make scientifically important observations. This limited opportunity and the potential scientific impact of the observations together constitute the justification for an exceptional response to a ToO proposal, by-passing the normal EVN review and scheduling procedures. The policy to apply for ToO time can be found [[http://old.evlbi.org/proposals/too.2011.pdf|here]]. Note that ToOs should not be submitted using NorthStar. Proposers should use the [[http://www.ira.inaf.it/evn_doc/covervlbi.tex|tex-based VLBI cover sheet]] to provide the observational details. Note that the proprietary period for ToO observations, during which the proposer has exclusive access to the data, is reduced to 6 MONTHS from the date of receipt of the correlated data from the last epoch of a proposal, see [[guidelines#EVN Data Access Policy|EVN Data Access Policy for further details.]]+Targets of opportunity (ToO) are defined to be extremely rare and/or unpredictable events where there is a limited opportunity to make scientifically important observations.

 Based on requests from the EVN user community, the EVN CBD has decided that the abstracts of any proposal (including ToOs and Short observations) submitted starting from the October 1 2017 deadline that receive observing time will become public at the EVN Data Archive (http://jive.eu/select-experiment). Based on requests from the EVN user community, the EVN CBD has decided that the abstracts of any proposal (including ToOs and Short observations) submitted starting from the October 1 2017 deadline that receive observing time will become public at the EVN Data Archive (http://jive.eu/select-experiment).

-"Short" e-VLBI observations may be requested for checking calibration or target source compactness in preparation for or as part of a larger VLBI observation or proposal. Projects requesting short observations must use standard observing and recording modes. They will be scheduled on a best effort basis.+Short requests (≤ 4 hours) are intended for short exploratory observations, such as checking calibrators or the feasibility of an observational setup, in preparation for a VLBI observation or proposal. Short requests are **not** intended as short scientific observations and will have **no proprietary time**; after correlation and pipeline calibration they become public through the EVN Archive. 
  
-Short observations (< 4 hours) may be proposed up to 6 weeks before an observing session begins. They can be proposed by means of a brief justification to the EVN Program Committee Chair (Kazi Rygl, INAF-IRA, kazi.rygl@inaf.it), who will, at her discretion, authorize scheduling in any gaps in the session plan, with the EVN Scheduler (Alastair Gunn, alastair.g.gunn@manchester.ac.uk) and JIVE (jops@jive.eu) in copy. +Short requests must use standard observing and recording modes. They will be scheduled on a best effort basis. The observing time (≤ 4 hours) should be justified in the request; shorter projects may be easier to schedule.

-Short e-VLBI observations may be requested for checking calibrator or target source compactness in preparation for or as part of a larger VLBI observation or proposal. These projects are limited to 2 hours or less in length. Such requests may be submitted up to three weeks prior to the start of any e-VLBI run directly to the Chairperson of the EVN Program Committee (Kazi Rygl, INAF-IRA, kazi.rygl@inaf.it), with copies to the EVN Scheduler (Alastair Gunn,  alastair.gunn@manchester.ac.uk) and JIVE (Bob Campbell, campbell@jive.eu and  Zsolt Paragi, zparagi@jive.eu). The EVN PC Chair will, at her discretion, authorize scheduling in any gaps in the session plan. There is no need to submit a full proposal via Northstar but e-mail to the Chair must clearly indicate the purposes and observing details of the proposed observation, as well as include information on proposed observing modes, stations/GST ranges and precise positions for all targets and calibrators. The information sent must be sufficient to allow central scheduling of the observations by JIVE personnel.+**e-VLBI**: 
 +Short observation requests may be submitted up to 3 weeks before e-VLBI run begins by email to the EVN Program Committee Chair (Kazi Rygl, INAF-IRA,
