GALFIT-CORSAIR: implementing the core-Sersic model into GALFIT
Abstract: We introduce GALFIT-CORSAIR: a publicly available, fully retro-compatible
modification of the 2D fitting software GALFIT (v.3) which adds an
implementation of the core-Sersic model.
We demonstrate the software by fitting the images of NGC 5557 and NGC 5813,
which have been previously identified as core-Sersic galaxies by their 1D
radial light profiles. These two examples are representative of different dust
obscuration conditions, and of bulge/disk decomposition. To perform the
analysis, we obtained deep Hubble Legacy Archive (HLA) mosaics in the F555W
filter (~V-band). We successfully reproduce the results of the previous 1D
analysis, modulo the intrinsic differences between the 1D and the 2D fitting
procedures.
The code and the analysis procedure described here have been developed for
the first coherent 2D analysis of a sample of core-Sersic galaxies, which will
be presented in a forth-coming paper. As the 2D analysis provides better
constraining on multi-component fitting, and is fully seeing-corrected, it will
yield complementary constraints on the missing mass in depleted galaxy cores.

):120-8.A study of some factors that influence the iodination of ox insulin., , .Abstract1. The influence of carrier iodide, iodine monochloride and pH on the labelling of ox insulin with (131)I by the iodine monochloride method have been studied. 2. The quantitative effect of the iodide in the radioactive iodine preparation was that predicted from a calculation of its specific activity. No other interfering factors were detected in the [(131)I]iodide solutions used. 3. Increasing the molar ratio of iodine monochloride to insulin resulted in an increase followed progressively by a decrease in the proportion of (131)I bound, while the total iodine bound increased to an amount characteristic of pH and thereafter remained constant. 4. The influence of pH on the iodination of insulin with iodine monochloride was complex and the pH curve showed two maxima, at pH2.8 and 6.4. At pH2.8 it was not possible to exceed 8 atoms of iodine bound per molecule by increasing the molar ratio of iodine monochloride. Similarly, at pH6.4 the substitution value of 11.5 atoms of iodine per molecule could not be exceeded. 5. Iodinated insulins containing an average of 1.96, 2.74, 6.0 and 7.0 atoms of iodine per molecule fully retained the ability to bind guinea-pig anti-(ox insulin) serum, and the ability to compete with unlabelled insulin for antibody sites only became significantly changed in the most highly substituted preparations and in the presence of large concentrations of unlabelled insulin. 6. The method for the iodination of insulin with 98% incorporation of (131)I by using chloramine-t is described. 7. (131)I-iodinated insulin prepared with graded quantities of chloramine-t in excess of that required for efficient labelling was less efficiently bound by guinea-pig anti-(ox insulin) serum than insulin labelled by the iodine monochloride method.PMID: 6033753
