| 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. |
