Would you please upload the test maps?

[Chunting]

Hi there,
No idea if you still maintain this project, but still wanna thank you in advance.
Would you please upload the maps for test purpose.

const std::array<const char*, 2> hector_maps = {
"map00.pgm",
"map05.pgm",
};

const std::array<const char*, 2> gmapping_maps = {
"2011-08-09-12-22-52.pgm",
"2012-01-28-11-12-01.pgm",
};

In my case, I run it on Ubuntu 18.04, ROS melodic, but the map merge does not work.
I set

<param name="known_init_poses" value="true"/>

However, there is always an translation in Y-axis in the merged map. No matter how to change the initial poses, the result does not make any difference, so I just wanna run the test cases to check the map merge algorithm.
Or would you please provide any other suggestions?
Thanks,
Chunting
