Xi from LRGs.dat #300

Closed schwartzw closed 2 months ago

schwartzw commented 11 months ago

Hi All,

I am trying to generate a xi function using the LRGs.dat file produced by the AbacusHOD module. How I am defining my coordinates are as follows: 

X, Y, Z = read_ascii_catalog(filename)

When I run the cell I get an error saying: 

Error tokenizing data. C error: Expected 3 fields in line 4, saw 6

I tried looking through the documentation for help but haven't found anything. Is my approach incorrect or am I using the wrong file to generate xi? If someone could help me with this issue and point me in the right direction, it'd be greatly appreciated. Thanks

-Weston

I would just use astropy.io to read the file; Corrfunc's read_ascii_catalog() probably expects a particular format. There's an example of using astropy.io here: https://abacusutils.readthedocs.io/en/latest/tutorials/light_cones/lc_hod.html#hod-on-halo-light-cone-catalogs

(I realize you're probably not using halo light cones but the file format should be the same)
