OMP Web page usage
OMP WEB PAGE CONTENTS AND
USAGE
|
|
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
|
From the UKIRT home page
sidebar, select Obs.
Management. |
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
|
|
At home page level. Links
get you into the "Feedback" system (via a project ID prompt), the Fault
system, and back to the home page.
The following three panels
show the sidebar as it becomes when you click on each of the three
links
here.
Note: "Project info" refers to the OMP project, not any observing
programme.
|
THE THREE TOP-LEVEL SIDEBAR STATES
|
|
At the Feedback System top
level. Note that in this example we've entered project ID u/03a/22, and
so
all of the links below the title line refer to this particular project.
Tip: If you return to OMP
home at this point, then select OMP Feedback system again (see the
panel above) you will still be looking at project u/03a/22 (the system
remembers). Use Logout (at the bottom) to disassociate yourself from
this project.
Tip: this sidebar contains virtually all the useful functions as far as
a remote PI is concerned. We suggest that you click each of these links
one by one and look carefully at the information displayed on the page.
This
is expanded upon below.
|
|
At the Fault system level.
Click on "UKIRT Faults" to get to UKIRT-specific faults.
|
|
At the UKIRT fault level.
Note the two new links, for filing and viewing faults, and the fault ID
textbox if you happen to know the particulat reference number of the
fault
you're after.
Note: this sidebar remains the same if you're filing or viewing a fault.
|
|
|
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.
|
Project
home
|
Administrative information on the programme, links to the science case
and Observer's summary page (not available outside JAC), and top-level
links to observation retrieval.
|
|
|
Feedback
Entries
|
Shows current MSBs in the database, and all comments on the programme.
Some of these are automatic, others are entered manually (either by
observers, the support astronomer, or by the PC for the programme).
|
|
|
Program
Details
|
This page reflects the current state of the observation database for
your programme. For each MSB in the database, it lists the content of
the MSB, the number of times it remains to be observed, conditions
requirements and its expected duration. These parameters are the same
ones as used to query the database by summit observers, so you should
ensure that they reflect your wishes.
|
|
|
Add
Comment
|
Here you add a comment into the feedback system (see two panels above -
these comments appear in that window). User ID is your OMP userid -
e.g. your surname followed (usually) by your first initial. Use this
page to enter generic comments about your programme's progress.
|
|
|
MSB
History
|
The observing history of your programme's MSBs. The example above shows
the first few MSBs observed on u/03a/22 - note that some of them were
simply retrieved from the database; others were retrieved, observed and
marked
as done. By default, all such activity is logged in this page. You may
not
want this much info, so the options in the "Show" box are All and Observed.
|
|
|
Contacts
|
Contact list. Update is used to change the "email" status of each named
contact.
|
|
|
OMP
Home
|
The obvious place.
Note: this is not the same
as Logout.
|
|
|
Faults
|
Faults specifically filed while observing this programme.
|
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:
- Login to your project home page (top link on the OMP page sidebar)
- Click on one of the UT dates for which data are listed as
having been taken
- 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.
Step 1 -
Select the UT date you want to get data for
|
|
Step 2 - go
there
|
|
Step 3 - get
the data
|
Click on "Retrieve data with calibrations" or "Retrieve data without
calibrations". The former retrieves all observations from the night
which had "flag as standard" ticked in the Observation box in the OT,
the latter omits those unless they are directly associated with the
programme in question.
