1 | Duchamp version 1.0.2 (2006/08/22) |
---|
2 | ---------------------------------- |
---|
3 | |
---|
4 | * The FDR setup routine was occasionally failing with a segmentation |
---|
5 | fault, due to it accessing unallocated memory. This has been fixed. |
---|
6 | |
---|
7 | * A bug that affected the propagation of blank pixel information to |
---|
8 | various functions (such as drawMomentMap) was fixed. The moment maps |
---|
9 | should now be correct in all cases. |
---|
10 | |
---|
11 | * Improved error and warning reporting, so that the formatting and |
---|
12 | presentation of information is clearer. |
---|
13 | |
---|
14 | * Fixed bugs that affected the way 2D images (rather than 3D cubes) |
---|
15 | were dealt with. The minChannels test failed when minChannels=0. |
---|
16 | |
---|
17 | |
---|
18 | Duchamp version 1.0.1 (2006/07/28) |
---|
19 | ---------------------------------- |
---|
20 | |
---|
21 | * A bug in the calculation of blank pixels has been fixed. The correct |
---|
22 | values from the FITS header were not propagating through correctly, |
---|
23 | meaning that the default values were being used. |
---|
24 | |
---|
25 | * The zoomed spectrum had its flux scale determined by all points in |
---|
26 | the zoom box,including those flagged by the MW range. This has been |
---|
27 | fixed so that any MW channels will not affect the flux scaling, |
---|
28 | potentially improving the appearance of objects detected close in |
---|
29 | velocity to strong MW emission or absorption. |
---|
30 | |
---|
31 | * The position resolution in the IAU-format names has been increased, |
---|
32 | so that distinct objects close to one another are more readily |
---|
33 | distinguished. Overlapping sources at different velocities may |
---|
34 | still have the same name, but this is a more general problem. |
---|
35 | |
---|
36 | |
---|
37 | Duchamp version 1.0 (2006/06/30) |
---|
38 | -------------------------------- |
---|
39 | |
---|
40 | The first full release version. |
---|
41 | |
---|
42 | Several major changes compared to previous version: |
---|
43 | |
---|
44 | * Incorporated a FitsHeader class, to keep track of header information |
---|
45 | (including WCS) from the FITS file. All units-related calculations |
---|
46 | are done with this class, such as conversion to velocity, and |
---|
47 | pixel-to-WCS conversion. The main advantage of this is improved |
---|
48 | speed of execution, more adaptable to different units, and improved |
---|
49 | code (easier for me!). |
---|
50 | |
---|
51 | * Able to select the dimensionality of the reconstruction, rather than |
---|
52 | just doing it in 3-D. |
---|
53 | |
---|
54 | * Robust text output, so that the columns are sized correctly given |
---|
55 | the data being written, and the relevant units (derived from the |
---|
56 | FITS header) are included in the output table. |
---|
57 | |
---|
58 | * Improved the way the reconstructed image is saved and read back in, |
---|
59 | with a better naming scheme and a better set of new FITS header |
---|
60 | keywords. The MW headers are now not written. |
---|
61 | |
---|
62 | Other, more minor changes include: |
---|
63 | |
---|
64 | * MW channels now not set to 0, but just ignored for searching |
---|
65 | purposes (and for the scaling of the spectral output -- they are |
---|
66 | plotted though and highlighted with a hashed box). |
---|
67 | |
---|
68 | * The scale bar in the moment map in the spectral output file has its |
---|
69 | length indicated. |
---|
70 | |
---|
71 | * Improved VOTable output, with more information about the way Duchamp |
---|
72 | was run. |
---|
73 | |
---|
74 | * Made sure all statistics calculations in the reconstruction are |
---|
75 | based on robust (ie. median) methods. |
---|
76 | |
---|
77 | Also moved to an autoconf based configure/make compilation, for ease of use. |
---|
78 | |
---|
79 | |
---|
80 | Duchamp version 0.9.2 (2006/06/27) |
---|
81 | -------------------------------- |
---|
82 | |
---|
83 | * Added the use of warning flags for detections: for either edge |
---|
84 | location or negative enclosed flux. |
---|
85 | |
---|
86 | * A new command line option added so that the user can specify a FITS |
---|
87 | file to be searched with the default parameters, rather than giving |
---|
88 | a full parameter file. |
---|
89 | |
---|
90 | * The scale bar on the moment cutout now works in general case, using |
---|
91 | an iterative process to get to the correct length. |
---|
92 | |
---|
93 | * RA axes are now done correctly on the full-scale maps. |
---|
94 | |
---|
95 | * Various coding fixes, improving the readability of the code, |
---|
96 | particularly regarding the declaration of temporary variables. |
---|
97 | |
---|
98 | * Changed the way the time of execution is called : now using time.h |
---|
99 | functions, rather than a system call. |
---|
100 | |
---|
101 | * Changed output in Detection/outputDetection.cc for the pixel |
---|
102 | information of detected objects (the info printed above the spectral |
---|
103 | plots) -- now print out number of voxels in object, and have |
---|
104 | improved the formatting a little. |
---|
105 | |
---|
106 | * Improved the functionality of saving the FITS file containing the |
---|
107 | reconstructed array. Added ability to save and read back in the MW |
---|
108 | parameters when saving a reconstructed cube (if a reconstructed cube |
---|
109 | has different MW range to that being considered, it would cause |
---|
110 | problems). ReadRecon now just returns a FAILURE and will reconstruct |
---|
111 | the cube anew. |
---|
112 | |
---|
113 | * Changed default value of flagGrowth to 0. |
---|
114 | |
---|
115 | |
---|
116 | |
---|
117 | Duchamp version 0.9 (2006/05/05) |
---|
118 | -------------------------------- |
---|
119 | |
---|
120 | First public release version. |
