Version History

IMPORTANT: when using BMODEL and GMODEL check that both refer to the same version!

• Latest version - version 2.2
• released 01/Aug/2008
• code does not hang anymore when unable to estimate the uncertainty in a given measured parameter
• minor bug fixed when reading uncertainties in BMODEL

• Version 2.1
• released 02/Jun/2006
• intensity parameters must be used now as pure counts (DN) and not normalized by pixel area as in previous versions
• when using BMODEL and GMODEL check that both refer to the same version
  
• faster and more reliable error evaluation, especially for fainter components and geometric parameters, but note that the error estimates for very faint components might be poorly defined, as always
  
• component fractions in current model summaries are better defined now and should sum up to 1 within numeric precision
  
• bug fixed when using maximum semi-major axis smaller than image size; now makes the code runs faster, as expected

• Version 2.0
• released 21/Mar/2006
• additional components: a Sérsic bar and a Moffat central source
• disks can be described with a double exponential
• more accurate routine for chi square minimization when considering random errors in the image, meaning more reliable results
• much better treatment of seeing effects, modelled as a circular Moffat PSF
• more accurate error evaluation
• bug fixed for ellipse indexes
• bug fixed for edge-on galaxies

• Version 1.0
• released Aug/2003
