WFCAM PROJECTS
PLEASE NOTE: WFCAM data
are processed at the Cambridge
Astronomical Survey Unit
(CASU) and served out via
the WFCAM Science Archive (WSA),
which is part of the Wide Field Astronomy Unit hosted by the Institute for Astronomy, Royal Observatory, Edinburgh. This applies to all
WFCAM data - UKIDSS, PATT, UH, Japanese, Korean and UKIRT
service programmes.
PROJECT STATUS
|
Project home
page
|
PATT, Service, UH, Japanese
and Korean PIs may follow
this link to their
project home page at JAC. You will be asked to login using the
project
ID (e.g. U/09B/H1, U/10A/J3, etc.). If you don't have one, please
request a password from here (or
contact your support scientist).
From this homepage you may view which MSBs have been observed (and
which remain in the queue), and gain access to observing logs, weather
stats, etc. for the nights when data were secured. NOTE: WFCAM data are
not available
from this homepage.
|
DATA PROCESSING
|
Data access timescales
|
PI project data are processed by CASU, usually within a few days of
arriving in the
UK (raw data are ftp-ed to Cambridge daily). Flat file access is
often made available within a month of
receipt at
the WFCAM Science archive, WSA.
NOTE THAT IT IS ESSENTIAL THAT YOU REGISTER YOUR PROJECT WITH THE WSA
AS EARLY AS POSSIBLE (see link below).

|
Progress of data reduction at CASU.
Each table also gives access to nightly plots and logs
of
seeing, zero-points, sky brightness, etc. These logs can be very
useful as a guide to the overall quality of your data!
|
Data ingest
status at WSA
|
Following pipeline reduction in Cambridge (at CASU), all WFCAM data are
transferred
to Edinburgh where they are ingested into the WFCAM Science Archive
(WSA). Use this link to check the ingest status at WSA.

REGISTRATION
|
You MUST register
your PATT, UH, Japanese, Korean
or Service project with
the science
archive. WSA refer to ALL
non-UKIDSS data as non-Survey (see
their sidebar). You will need your
project ID (e.g. U/SERV/9999, U/09B/J1, etc.) and the project title.
You will be
informed by the science
archive (via email) when your data are ready for retrieval.

non-UKIDSS observer -
PATT, U.H.,
Japanese and Korean)

Disk
connection policy
|
A policy statement on external disk connections at the
summit, and notes on other ways to copy raw data directly. (This page is on the Public Wiki.)
|
|
|
Raw WFCAM data can be provided on a best-efforts basis direct
from the
CASU near-line archive. Note that you will need to be registered; this
page gives contact information for this. |

CASSEGRAIN PROJECTS
The links below DO
NOT APPLY TO WFCAM. UKIRT's suite of cassegrain instruments include
UIST, UFTI, CGS4 and the polarimetry module, IRPOL.
UKIRT flexed Cassegrain data are available from the UKIRT OMP feedback
system.
To retrieve data for your PATT programme, you will need:
- The proposal ID (usually u/semester/nn; note
that if your project id number is below 10, you must not add a
leading zero)
- The proposal password (if you don't know the password for your
project, then you can ask for a
new one to be sent to the project PI here.)
The table below gives (i) a brief reminder for those who have used the
system before, with a link to the data page, and (ii) links to the
detailed
documentation.

RETRIEVAL
|
Retrieve and
view project data
|
- Follow the link to the left, which takes you to your
project home page (you will be asked to login using the ID and password
as above)
- Note the list of MSBs observed (if N(repeats) is set to
zero, the MSB was only fetched, not executed)
- Click on a UT date to access the data for a given
night
Then either
- Click on "Retrieve data with calibrations" or "Retrieve
data excluding calibrations" (the former will give all photometric
calibrations for the night; the latter will give all calibrations
associated
with your programme only).
or
- Use the links at the righthand end of the night's
observations
table to view selected reduced frames. Note that these frames remain on
disk
only for a week or so.
