This is the README file of the HELP WP4 release V1.1 of WISE data. 

Version 1.1 supersede version 1.0. It fixes a bug that resulted in the 
catalog being extracted on a mask where x and y axis where swapped. Note
that this does not mean that the information in version 1.0 catalogs is 
wrong. All their sources and measurements is correct, but the sources are
not all in the intended region.


Detailed informations can be found at:
http://fp7census.pbworks.com/w/page/100423837/WP4_WISE 

The release contains a subset of the AllWise data release, selected to
be within the footprint of the SPIRE coverage of the HELP fields,
available at 
http://fp7census.pbworks.com/w/page/87735187/SPIRE%20Coverage%20Maps

Note that since there is no complete mask for the Helms+HERS region
(now Herschel-Stripe-82), the corresponding catalog is incomplete.

The following table list the number of sources in each individual catalogs.

Each catalog contains the following columns. All columns have propers
units, description and ucd within the FITS table. The short
descriptions provided below are for information only. See
http://fp7census.pbworks.com/w/page/100423837/WP4_WISE for a complete
description of the columns.

Note that the error on fluxes are computed following as different
prescription than the one described in the standards v1.1 document.
