LIST:
antiblooming2.pro
cccpy.pro
density_map6.pro
double_gauss_fit.pro
plotxyz.pro
smearer.pro
antiblooming2.pro
This program corrects astronomical images from blooming effects (saturation)
cccpy.pro
This IDL program (calling a python function) can be used to match
two catalogs using their RA and DEC positions.
This progam is based on the same principles of cccpro.pro (Written
by Mattia Vaccari), but the cccpy function works in a much more
efficient (faster) way when using big catalogs (>100 thousand entries)
Principle:
This program writes a python program in a temporary file called
"cccpy.py". The indexes and coordinates are passed from IDL to
python and vice-versa through two temporary files: tmp0.txt and
tmp1.txt.
At the end of the process, all the temporary files are deleted.
density_map6.pro
overplots (output file) a color density map, given an input list of x, y, datapoints
double_gauss_fit.pro
Given the x and y values of an histogram (xhist, yhist),
it finds the best fit for a double gaussian distribution trying
different peak and sigma values.
plotxyz.pro
This function works as an "oplot" function. Overimposed to the input
x,y positions, it draws bigger (and color-scaled) circles for higher
values of z.
smearer.pro
It creates a set of x, y, z elements randomly distributed (gaussian)
around an input list of x, y, z values.
density_map5.pro is replaced by density_map6.pro.
some minor bugs of the previous version are now corrected;
Z_TYPE "ran" option is added.
