The OMP web pages give access to all available information on Programme completion, MSBs executed etc., and also provide remote users access to their data. This document discusses the functions available and gives worked examples of external PI’s use of the system. The examples are essentially UKIRT-specific but the principles are the same. 

Document Sections:

Accessing the system

The OMP Sidebar

Understanding the sidebar once into the OMP pages is crucial to your successful use of the system. The contents of this bar change depending on where you are in the system:

HOME PAGE SIDEBAR

THE THREE TOP-LEVEL SIDEBAR STATES

PROJECT HOME (“FEEDBACK SYSTEM”) SIDEBAR AND USES

The following panels show typical pages seen when clicking down through the project feedback sidebar entries for a given project.

Viewing data and eavesdropping on observing in progress

For a limited period after the data were taken (typically a week, but beware that this is dependent on disk space at the summit) you can view the reduced data products from the summit pipeline via the project log pages. Here is the basic sequence, following which we show screen shots for an example programme:

1. Login to your project home page (top link on the OMP page sidebar)
2. Click on one of the UT dates for  which data are listed as having been taken
3. In the resulting list of observations (below the MSB list) click on one of the data product links, which are at the righthand end of the observation list table.

For spectroscopy, the reduced group image is the _group (the same _group is linked to from the end of each frame’s line). For imaging, the reduced group is the _mos (mosaic) image.

Note that if you have a tabbed browser (Mozilla or Netscape 7 for example) then you can set it to open a new tab when middle-clicking on a link; this will save you from reloading the observation list repeatedly in order to look at more than one image/spectrum.

In detail, with screen captures for an example programme (the detailed appearance of some of these pages is subject to change but the basic idea will generally be as shown here):

Step 1 – go to the project home page

Step 2 – select a given UT date

Step 3 – Inspect the Observation list

The example below shows only the extreme left and right edges of the table. Note the _group links for the final reduced spectroscopy group, and _wce for the individual frames. These links all take you to a WORF page for closer inspection.

Step 4 – Inspect the data

For example, a spectral image:

…and the same image after selecting a horizontal cut:

Since February 2005, we also provide links to FITS and NDF images, and an Aladin viewer. These are all accessible from the WORF page:

Aladin (added February 2005)

The Aladin viewer is particularly useful for inspecting reduced imaging products (at the time of writing, it is only available for imaging). Please note that a normal mosaic image can take tens of seconds to load – check the image stack at the right hand side of the Aladin display.

Retrieving data

Data can be retrieved from the OMP system in three straightforward steps. As with all operations relating to your project, everything starts from your project home page, so log into that first.
