Data from BOSS -- Masks

Boss Data was downloaded from the public release DR10 from the following website
http://data.sdss3.org/sas/dr10/boss/lss/

The masks are the following:
mask_DR10v8_CMASS_North.ply
mask_DR10v8_CMASS_South.ply
mask_DR10v8_LOWZ_North.ply
mask_DR10v8_LOWZ_South.ply

The exclusion areas within are :
badfield_mask_postprocess_pixs8.ply
badfield_mask_unphot-ugriz_pix.ply
bright_object_mask_rykoff_pix.ply
bright_star_mask.ply
bright_star_mask_pix.ply
centerpost_mask.ply
collision_priority_mask.ply

Script script_runBOSSmasks.sh
runs the masks from an ra dec input.
See header for info.

Meeting Minutes - 25th July

Github and wiki:
people are a little but not very acquainted with github.
We are going to use it anyway
People make a branch first, and only merge to the master branch once agreed with everybody

We will move the repository to UCL Github

One can use ipython notebook and upload the files

There is a list of ignore files like .mod etc

Splinter:
We should get a data in splinter

Discussion:
- Sree
: needs density map, and corresponding noise map, and covariance
what happens with pixels with zero galaxies? -> needs discussion
how do the code work

General question
how to treat masks and produce healpix maps:
a) do high resolution healpix and then ungrade
b) weight galaxies with their weights as quoted by boss

For next meeting
- a map from boss with binary mask and Poisson Shot noise from BOSS and DES.
