How to submit

Step 1: Download and test

The PATT2 form template, style-files and an example form are available here (latest version is 02/2013):


Save this tar file to your local computer, or alternatively you can grab it using:


and unpack it using:

tar zxvf PATT2_Pack.tar.gz

The tar file contains eight files:

  • the PATT2 form template, patt2_blank.tex (and compiled
  • the PATT2 style-file, patt2.sty
  • an example form, patt2_example.tex (and compiled
  • an example PostScript figure,
  • a style-file for embedding level-2 PostScript figures, psfig.sty
  • a style-file for embedding encapsulated level-2 PostScript figures, epsf.sty
To see how the example form looks, simply run Latex on the source file:

latex patt2_example.tex

To display it on your screen:

xdvi patt2_example.dvi

To create a PostScript version:

dvips -o patt2_example.dvi

You can then compare the file compiled by you,, with the provided

Step 2: Edit

To create your own proposal enter the proposal details between the keyword brackets { } in the template, patt2_blank.tex. Refer to the example form if you are unsure of any details, such as how to embed PostScript figures.

Font sizes should not be reduced from the style-file defaults, and likewise the typeface must not be changed (bold typeface is acceptable). Proposals written in a smaller font or different typeface will not be accepted.

The PATT2 style-file, patt2.sty, and if used, the PostScript style-files psfig.sty and epsf.sty, should not be edited; applications are processed at ING with the original versions of the style-files.

If you include figures, they should be located in the working directory, i.e. do not put a local path to figures in your application form. This path would not, of course, be recognised on our system when your proposal is processed. Colour diagrams and images are acceptable but please make sure that they look fine when printed in black and white.

Figures larger than 5 Mb (uncompressed size) in total should not be submitted. If you are unable to provide figures within this limit, you may include a URL in your proposal pointing to such figures, so that they can be viewed by referees and assessors (colour diagrams and/or images may also be referenced by URL). This is at your own risk.

Step 3: Submit

Send the completed proposal (the Latex source file together with any PostScript figures) as separate uncompressed attachments in a single email to:

and state in the subject line: "WHT Proposal" or "INT Proposal".

Please do not attach a tar file, or include the Latex source file in the body of the message (send the Latex source file as an attachment to your submission email instead). Additionally, you may also attach the compiled PDF version of your proposal, but please note that the Latex file together with any accompanying figures is the main submission. Do not submit a PDF file alone.

On submitting your proposal, you will receive an automatic acknowledgement, and within a few days you will receive confirmation that it has been processed, and its PATT reference number. Quote this reference number in any future correspondence concerning your proposal. Please contact if you don't receive the acknowledgement and confirmation messages in a few days.

Scientific feedback will be sent to PIs by the Swindon PATT office a few weeks after the Time Allocation Panel has met.


The web page applying for telescope time provides general information on how to apply for time on the ING telescopes.

The instrumentation available on the WHT and INT is summarised on the ING instrumentation overview page. Applicants planning to submit a proposal based on a new (to ING) visitor instrument should follow the procedure for new visitor instruments.

For standard proposals the science case should not exceed one page. Text which exceeds this limit will not be read by the panel, and this may adversely affect the grade awarded to your proposal. Proposals to the WHT or INT which are coordinated with other non-ING telescopes, may use a two-page scientific justification.

For eight or more nights on the WHT the PATT2 application form allows a two-page scientific justification. Proposals to the WHT or INT which are long-term, that is which request an allocation (not necessarily eight or more nights) over more than one semester, may use a two-page scientific justification. Observing programmes of less than one night are not accepted on either the WHT or the INT unless agreed in advance by the Director of ING or the Head of Astronomy. For such programmes, please consider applying for service observations.

Applications for override programmes should be submitted to the PATT in the same way as proposals for scheduled time, and will be judged and ranked by the PATT head-to-head with such proposals.

As part of the assessment process, each proposal is assigned to a referee external to the time allocation panel for evaluation. If you have submitted a proposal to the panel in the current or in a recent semester, you may be asked to undertake such a role.

The UK PATT will accept proposals from a PI employed or studying in countries other than UK. Such international proposals may be assessed by UK PATT, or at its discretion may be passed to an international TAC comprising members of the national TACs, or to the correct national TAC, if the PI is based in a partner country.
