version 4.8.2, 2010dec17:
25
- Added parallelization of WFS (i.e. one thread/WFS in a multi WFS system)
26
- Tried implementing FFTW parallelization, but the gains were really marginal
27
and often it would be more detrimental than good. Reverted, but left the
28
code commented in Makefile, yao_fast.i and yao_fast.c
29
- yao now looks for and includes yao.conf, if any (before was only in yao GUI)
30
- changed all calls to fitsRead and fitsWrite to new function names
31
yao_fitsread and yao_fitswrite. This way, I work around any conflict
32
with fits.i function checks. Renamed newfits.i to yao_newfits.i
33
- fixed a number of bugs in svipc implementation (mostly how it recovers from
34
a previous svipc run within the same session). test-all.i now runs good
35
with sim.svipc = 1, 5, with wfs.svipc>1, as well as sim.svipc=1 *and* wfs.svipc>1
37
- added items in check_parameters() to check for the svipc bad settings
38
- re-introduced sim.name in graphic and nudged some labels in graphics a bit
39
- introduced some changes to make the graphic look better when using
40
xftfonts. also resized controlscreen
41
- better handling of window closing/opening when using svipc
42
- push to get reference tip is now 0.005 instead of 0.05 (there's no noise)
43
- fixed a bug that animate would not be ON for display in close loop when
45
- switched the Makefile to -Wall
46
- 2 new sim structure members: sim.svipc_wfs_nfork and sim.svipc_wfs_forknb
47
- fixed a bug in pyramid wfs, hopefully once and for all (bad sinc() function
49
- added test3.par (same as glao.par)
50
- fix a bug in test5.par (phase screen referred in parfile may not have
52
- fixed issue with animate being ON and preventing further plot
53
- fixed bug in which background calib was not passed to wfs.svipc child (since
55
- fixed nitegcycle for shwfs when no svipc
56
- written test routine (examples/test-fr.i) to check correctness of main
57
modes of svipc (wfs and sim).
60
version 4.8.1, 2010dec06:
61
- changed layout of graphic window to add residual phase
62
- display of residual phase (Marcos)
63
- nintegcycle in pyramid wfs (Marcos)
64
- "extended" object in pyramid wfs (Marcos)
65
- a couple of bugfix (Marcos and I)
68
version 4.8.0, 2010nov09:
70
* increased size of axis labels fonts on plsys(4)
72
* fixed error handling. Now error in place, instead of calling error handling
73
function (exitInError). Allows much clearer debugging.
75
* merged pyramid_wfs() changes from marcos, upgraded my francois
76
* changes in yao main routines to make re-introduced obsolete "pyramid" wfs type
77
* upgraded GUI to include pyramid modulation amplitude control
78
* added 4 new structure members to wfs structure
80
* added "--dpi ##" command line call option (for GUI call). Example:
81
yao --dpi 75 sh6x6.par
82
* added default animate() to iMat acquisition display.
83
* cleanup of yao.py (dictionary autoconnect) + dpi stuff
84
* shortened get_style() calls to viewport() call
85
* gotten rid of get_processor_number() (use nprocs() function in svipc)
86
* added a bunch of extern wfs, dm, ... in functions called by python to set
87
values of parameters (how could it have worked before is a mystery).
89
* fixed a bug in which the graphic would get stuck (animate call was done
90
without ensuring a plsys,1)
94
version 4.7.3, 2010 oct12:
95
- merged SH threshold methods #2 and #3, patches from Yann Clenet
96
Credits for original idea of method #3 (compute centroid on N
97
brightest pixels instead of using a flux threshold) go to E.Gendron.
98
- added some safety for the choice of shthreshold when using shmethod=3
99
to avoid getting segfaults in yao_fast.
101
version 4.7.2, 2010 oct12:
102
- added smooth animate=1 for iMat recording/display
103
- added ETA when taking iMat
104
- added option to findfwhm() to save RAM requirements (help,findfwhm)
105
- merged patch from Marcos van Dam:
106
* implemented virtual DMs for tomography
107
* implemented save of residual phase in go() (help,go)
109
version 4.7.1, 2010sep16:
110
- fixed nasty bug that was not switching noise off for background calib (SHWFS)
111
Thanks Yann Clenet for noticing and pointing me to the right direction
112
- make screen now can drop the imaginary part (no_ipart=1) to produce larger
113
screens by saving some RAM.
114
- Gotten rid of hdf5 call in yaodh (and thus of hdf5 dependency)
115
- switched the default mode in test-all.i to non svipc
117
Version 4.7.0, 2010aug14:
119
- Merged a bunch of changes from Marcos van Dam. From his changelog:
120
1. There is a new version of soy.i. I found more bugs and since it had to be modified, I added new functions. FR: I merged these changes in soy 1.3
121
2. filtertilt set to 0 for interaction matrix generation. I need this to generate sparse matrices.
122
3. filtertilt for zernike and stackarray DMs. I need to filter tilt from DMs when doing tomography with LGSs.
123
4. WFS measurements set to 0 if not from same subsystem as DM.
124
5. minimum zernike (to exclude piston/tip/tilt if desired). I need this feature for tip-tilt tomography.
125
6. I remove the reporting of the number of corrected modes... do we really need this? it makes no sense for anything other than classical AO.
126
7. pupil (real = 0). We discussed this earlier.
127
8. Introduced virtual DMs needed for tomographic reconstruction
128
9. mmse and mmse-sparse works fine with MCAO
129
10. Have loop.method set to closed-loop, open-loop and pseudo open-loop. Open loop means WFS sees uncorrected WF, not corrected WF.
130
11. Tomographic reconstruction!
132
- Fixed a broken re-opening of graphic window because of undefined dpi.
134
Version 4.6, 2010jun17:
136
- Merged Aurea Garcia-Rissmann additions for diskharmonic DMs
137
Part of the code from Mark Milton (at the time at UofA). Used
140
- Merged parallelization code (svipc). Can lead to 3x gains on
141
multicore machines. Tweak with sim.svipc = value (see yao_structures)
143
- Gotten rid of redondant code in utils.c. poidev was in there, as well
144
as other routines. These are already in imutil and imutil is definitely
145
a dependency. This, combine with using the latest imutil v 0.5.6, solves
146
a bug in which poidev would SIGFPE when using too brights GS in with
149
- solved a bug in which not specifying skymag would means skymag=0
150
and thus lots of photons in the sky in CWFS mode. Now skymag=0
151
(default) is interpreted as "no sky".
153
- upgraded all the PROTOTYPES to new recommended syntax "type array"
154
instead of "pointer".
157
- changed "least-squares" -> "mmse"
158
- changed "sparse" -> "mmse-sparse"
159
- updated documentation with input from Marcos Van Dam
