PSM release 1.7.0-beta

About this version

This is the first released version of the PSM after complete revision of the software. Most of the code has been updated or rewritten, the general structure has been redesigned. The major changes are:

Complete separation of the generation of the sky model from its observation with an instrument
Better interfacing with CAMB for Gaussian simulations (more cosmological parameters, better handling of the accuracy of the CAMB runs)
New non-Gaussian CMB simulations
New implementation of CMB lensing
Simulation of dipole emission now included
New model of SZ emission based on constrained hydrodynamical simulations up to z=0.25, complemented by clusters from a mass function at z>0.25
New cluster mass function and updated cluster physical modeling
Revised Galactic emission
Now component for CO molecular line emission included
Possibility to observe sky emission integrated in Planck frequency bands
More sophisticated instrument models
Implementation of WMAP sources
Easier access to PSM data, with automatic download of necessary data sets during the PSM run
Improved headers for PSM maps
Improved handling of seeds for random number generation
Improved handling of temporary files
Extended toolbox

There are still a number of loose ends, for instance:

The documentation is uncomplete
Models have been unevenly tested
Some of the previous models for galactic emission have not been maintained (but they can be reactivated if needed, although not on a very short timescale)
The generation of small scales for spinning dust has been turned off, as it generated unphysical oscillations in the maps. Hence the spinning dust map does not contain small scales. This still has to be fixed.
Polarised SZ effect not fully operational
The contamination of clusters of galaxies with radio and infrared sources is not fully implemented.

30 August 2011 The version number written in the PSM outputs is 1_7_0, instead of 1_7_0-beta as it should. The next release will be 1_7_1 to avoid any ambiguity.
30 August 2011 Bug in tool psm_alm2map.pro, ORDERING keyword not properly written in header when output is in NESTED format. Replace the "psm_alm2map.pro" file in "Soft/tools/sht/".
Note: this is necessary only if you use the PSM toolbox independently of PSM runs (the PSM currently only writes HEALPix maps in RING format). psm_alm2map.pro v1.37
01 September 2011 The parameters for the generation of small scale fluctuations in galactic components have to be revised. Use v1_7_1.
02 September 2011 The PSM run fails during the generation of the FIRB component if the !PSMROOT directory name does not end with the / (slash) separator. This is fixed in next releases. For v1_0_7-beta, just make sure the !PSMROOT directory name does end with the slash separator.
28 September 2011 The PSM run fails if the parameter 'OBS_TASK' is not set in the configuration file (no valid default value). Always define 'OBS_TASK' ('new', 'update' or 'none').
29 September 2011 There is a memory leak in band integration, that causes the PSM eventually to fill the available memory for large scale simulations. Replace the "sky_in_bands.pro" file in "Soft/observation/skyobs/". sky_in_bands.pro v1.26
12 October 2011 Small scale galactic emission is wrong for nside=2048. Replace the "add_smallscale.pro" and "file2ptr.pro" files in "Soft/skymodel/galaxy/", and the "gal_sys_var_init.pro" file in "Soft/skymodel/galaxy/general/". add_smallscale.pro v1.7 file2ptr.pro v1.8 gal_sys_var_init.pro v1.19
08 May 2012 Bug in WMAP sources (excessive flux due to units error for sources not detected in K band) Replace the "psm_wmap_sources.pro" file in "Soft/skymodel/ps/". psm_wmap_sources.pro v1.16
