A few suggestions to the database:
1) A way to see what are in the database without searching. Right now
you have a few patterns there, if I search with some keywords, I will get
zero return. It is beneficial If we have a way to scan through the entries.
2) A way to store and retrieve refinement results associated with a
particular pattern.
3) A way for people to put their comments on a refinement

Armel,
Not bad for a few hours work! I hope that everyone gives some
feedback because
this is a great opportunity to decide what we as users want in a
database.
Perhaps we should also return to one of the old chestnuts (quaint
English
expression that means 'classic argument') from the powder
diffraction meeting
a while back- should we standardise the data by presenting it in d
or q
(irrespective of whether the fit was done in 2theta or TOF, etc)?-
This can
only simplify comparisions of data.
Can I make a few suggestions:
1) Give the wavelength(s) in Angstroms, with ratios, so that lab
source and
neutron people can understand each other (Cu k-alpha and PG(002)
both require
'specialised' knowledge).
2) Allow the reader to browse through the formula.
3) If people are to quickly check out the data we either need to
have some
standardised viewers (or data format), or a ps/pdf/jpeg picture of
the
pattern. Again d spacing or q might be useful to aid comparisons
between
wavelengths.
Lachlan what suggestions do you have for viewers?
Bonne chance,
Andrew
