While both the intensity and covariance quantities presented in the Planck all-sky maps are, by definition, positive, there are situations in which you will see negative values. o In regards to the Planck intensity maps: To begin with, the Planck...
The Planck map products express intensity in three different (and frequency-dependent) forms: K_CMB (thermodynamic temperature), K_RJ (antenna temperature, also know as Rayleigh-Jeans temperature), and MJy/sr. The attached memo addresses the definition...

The SMICA maps are multi-extension FITS files containing the CMB (in the 1st extension) then the residuals at each band in the 2nd and 3rd extensions. The CMB units are uK_CMB as stated in the headers. For 30-353 GHz the map residuals are map-CMB = for...
To uncompress the files you have downloaded from the command line, type "unzip .zip". To uncompress multiple files at once, type "unzip '*.zip'" (the single quotes are important), or "unzip \*.zip" -- you just have to escape out the wildcard. Double...
Here are some tips for making your large catalog search return faster: 1. If you suspect that your query might return results larger than 2 Gb, you will need to break it up into smaller queries. It can be difficult to predict the size of the returne...
