WFCAM PROJECTS
WFCAM data are processed at the Cambridge Astronomical Survey Unit
(CASU) and served out via a
science archive at the Wide Field Astronomy Unit, Edinburgh
(WFAU). This applies to all WFCAM data - UKIDSS, PATT and UKIRT
service programme.

PROJECT STATUS
|
Project home
page
|
- 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)
|
DATA PROCESSING
|
Data Access Timescales
|
PI project data are processed by CASU within a month of arriving in the
UK, and flat file access is made available within a month of receipt at
the WFCAM Science Archive at WFAU.
NOTE THAT IT IS ESSENTIAL THAT YOU REGISTER YOUR PROJECT WITH THE WSA
AS EARLY AS POSSIBLE.
|
Data
Processing Status at CASU
|
Access to tables listing progress with data reduction, plus (per
night) data quality control plots (seeing, zero points etc.). Use this
table to track the progress of your data set through ingest, pipeline
processing and transfer to the WFAU science archive.
|
Raw data archive
|
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.
|
SCIENCE
ARCHIVE
|
Science
Archive Registration
|
Register your PATT, UH, JP or service project details with the science
archive (this is
where you will set up a user ID for your project and is a prerequisite
to subsequently retrieving your reduced data). You will need your
project ID (e.g. U/SERV/9999) and the project title. You will be
informed by the science
archive when your data are ready for retrieval (there is also a status
table which shows whether data are in the archive).

Science Archive

Home page of the WFCAM science archive. Provides user documentation,
information on queries, cookbooks and access to data.

CASSEGRAIN PROJECTS
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.
