CDS Planning from RAL:
May 13, 2002

At present, new CDS planners who are non-US citizens require an escort at GSFC, which can be restrictive both for the planner and the local GSFC personnel.

Anyone who wishes to be a CDS planner outside the periods of the Medoc campaigns, may consider planning from RAL as an alternative to travelling to GSFC. This could be a particularly convenient and cost-saving option for UK-based scientists. All first-time planners are provided training at RAL before their planning week, and local support will be given during the planning week.

Please contact Andrzej to inquire about the current planning schedule and to arrange dates.

In my experience, being a planner during your own campaign or joint observing programme offers a considerable advantage in that it affords you direct control over target selection and pointing, in response to current solar conditions. I would like to encourage everybody, particularly PhD students and post-docs, to consider this hands-on way of acquiring data for your research projects. - Andrzej Fludra


CDS User Guide:
May 13, 2002

This is a reminder that the CDS User Guide is available at:
http://solg2.bnsc.rl.ac.uk/software/uguide/uguide.shtml

ANYONE WHO WANTS TO PROPOSE A NEW CDS STUDY OR BEGIN THE DATA ANALYSIS IS STRONGLY ENCOURAGED TO CONSULT THIS MANUAL.

Users who find things they don't understand, or that don't work, or information that is missing, should contact a member of the RAL CDS team (for example, Dave or Andrzej). Your feedback is very important to us, as we cannot solve problems we do not know about. We will endeavour to solve any problem that is brought to our attention. - Andrzej Fludra


SOHO Archives:
May 13, 2002

The User Guide also contains information on browsing and retrieving CDS data, in particular, links to SOHO archives at RAL, in the USA and France.

Here are direct addresses of these archives:
http://trace.solararchive.rl.ac.uk/soho/ - RAL
http://sohowww.nascom.nasa.gov/catalog/ - USA
http://www.medoc-ias.u-psud.fr/archive/ - France

Please note that the RAL archive and the USA archive have different interfaces. They are reasonably intuitive and include links to their respective Help files. Should you encounter an insurmountable problem when accessing the archives, please email your questions to the local archive administrator listed on each website. - Andrzej Fludra

CDS Diary

Due to a recent reorganisation of responsibilities, the CDS Diary (the 'Requests' entry on the CDS Web pages) is now edited and maintained by Andrzej. Requests for future observations should be sent directly to Andrzej and copied to Richard as usual.

NIS full spectral plots
Thursday, 19 Jul 2001

By popular request, the CDS Atlas displays for the NIS full spectrum (NISAT_S) data have been converted to spectral plots instead of wavelength-integrated images. The data have been cleaned, calibrated, plotted on a log scale and reverse videoed to ease line recognition and printing.

They have also been extracted as a specific group of data and may be selected as such from the CDS Atlas main web page.
