saving/restoring data - single hdf file for spec data and ctr results.
-
Add ave funcs (plane groups) to CTR data
-
Attenuation factors
-
Rocking scan integrations (peak module)
-
Bug in point selection from hk plot??
-- images --
-
Polygon (ie arbitrary) image rois?
-
Two image rois - one for bgr, 2nd for integration?
-
Make fcns for (re)correcting 'bad pixels'.
-
look at how bad/missing images are handled during read
-
convert images to recip space coordinates
- calc rot angle to keep L projection along horizontal and model peak widths in order to improve automation of integration.
- Need detector distance, pixel spacing, pitch, yaw and roll. Therefore, need an algo for solving detector parameters:
- Define pixel center at 0del and 0nu. then give direct beam pixel position at 4 different del and nu settings. From these refine distance and 3 angles. (note if do with diffraction peaks from known sample can also refine lambda and axis offsets...)
- pixel hkl
- gonio calcs - more geometries... and calc angles given constraints...
- lsq optimize of lattice params (and axis offsets)
- In geom code add a warning about parallel reflections in calculating the UB
- background: Add smoothing / rebin option for backgrounds
- use compiled code for bgr / fitting
- apply in xrf module
- numerical peak integrations
- work on xrf_plot (and med plot)
- error bars for xrf data / peaks
- use peak.background in xrf
- note no reason to opt bgr params....
- speed up fits (get rid of nmfit)
- generic structure factor calcs
- Output penetration depth
- Note include thin film and transmission cell modes
- Add routine that will step through theta and build matrix of I, etc, for plotting. i.e. make 3D plot like matlab code
- Fitting interface models, linking paramters, fit mult data sets etc...
- Interface for
f',f'' and mu's(use xraydata library??)
- surface symmetry and surface model generator
- dictionary of space groups from international tables
- dictionary of transforms from international tables
- plane groups
- etc....
- read cif files.
