API changes in version 1.3.0

Pyplis version 1.3.0 comes with many new features and major improvements in user-friendliness and performance (compared to previous release 1.0.1). In the following, a brief overview is provided over the most important changes associated with this release. Please see latest changelog for a detailed description of all changes.

• Measurement geometry (class MeasGeometry):
  • more accurate plume distance retrievals (i.e. now also in dependency of vertical distance).
  • redesigned API -> improved user-friendliness.
• Image analysis: Image registration shift can now be applied to images.
  • New method shift in class Img.
  • Comes with new mode (shift_mode) in class ImgList objects.
  • Default on / off shift for camera can be set in class Camera using attribute reg_shift_off (and correspondingly, in file cam_info.txt).
• Camera calibration. Major improvements and API changes:
  • new abstraction layer (module calib_base) including new calibration base class CalibData. Both class DoasCalibData and class CellCalibData are now inherited from new base class class CalibData. Advantages and new features:
    • arbitrary definition of calibration fit function.
    • fitting of calibration curve, I/O (read / write FITS) and visualisation of DOAS and cell calibration data are now unified in class CalibData.
• Further changes
  • class ImgStack more intuitive and flexible (e.g. dynamically expandable).
  • Improved index handling and performance of image list objects (module imagelists).
  • class PlumeBackgroundModel: revision, clean up and performance improvements.
  • Improved user-friendliness and performance of plume background retrieval in class ImgList objects.
  • Correction for signal dilution (class DilutionCorr): increased flexibility and user-friendliness.
  • Improved flexibility for image import using class Dataset class (e.g. on / off images can be stored in the same file).
  • Reviewed and largely improved performance of general workflow (i.e. iteration over instances of class ImgList in calib_mode, dilcorr_mode and optflow_mode).
• Major bug fixes
  • Fixed conceptual error in cross-correlation algorithm for velocity retrieval (method find_signal_correlation in module plumespeed).
  • Fixed: class ImgList in AA mode used current off-band image (at index idx_off) both for the current and next on-band image (and not idx_off+1).
