This dataset contains source files for generating the cross-identification between Cordoba Durchmusterung catalog (declinations -22, -23 and -24) and PPMX catalog. The resulting catalog lies in the file cat/new_cd.txt and its format in the file cat/new_format.txt


Steps to reproduce

The main algorithm generates an instance of a problem called 2-Matching (a generalization of the Matching Problem). Then, it decomposes that instance into several components that are solved separately. Each component is solved via integer programming by using the state-of-the-art solver GuRoBi. A diagram is provided to show the different steps of the cross-identification process (see diagram.png). This piece of software requires GuRoBi 6.5.2 and the WCSTools 3.8.7 library, which can be donwloaded from: 1) 2) Before compiling, insert the content of wcstools-3.8.7\libwcs into the folder libwcs. Then, do the following: 1) Add the following line to the file wcscon.c (after the line #include "wcs.h"): #define strncasecmp(x,y,z) _strnicmp(x,y,z) 2) Comment the line 375 of the file wcslib.h. For instance: // int wcsset(), wcsfwd(), wcsrev(), wcsmix();
