Implemented the addition of two cuts to study the effect of redshift errors (zerr-cut-deg and zerr-cut-kms). The meaning of these two parameters differs depending on whether we measure the auto-correlation or the cross-correlation.

For the cross-correlation:

  • zerr-cut-deg: Related to the angle between the skewer and the quasar object.
  • zerr-cut-kms: Related to the radial velocity difference between the skewer's quasar and the object.
    Skewers from quasar pairs where (θ < zerr-cut-deg) and (v < zerr-cut-kms) are removed from the computation.

For the cross-correlation:

  • zerr-cut-deg: Related to the angle between skewers.
  • zerr-cut-kms: Related to the radial velocity difference between a pixel in one skewer vs the other skewer's quasar.
    pixel pairs where (θ < zerr-cut-deg) and (v < zerr-cut-kms) are removed from the computation.

Opened this draft pull request to discuss the election of variable names, behavior or any other issue.
