Cosmological Parameter is one of roughly 13 parameters used to define standard models
Fiducial value is the value of the cosmological parameter used in the simulation
MAP is the Microwave Anisotropy Project a selected MidEX program.
C/S HFI is the COBRAS/SAMBA High Frequency Instrument(bolometric instrument)
C/S LFI is the COBRAS/SAMBA Low Frequency Instrument (HEMT amps)
Red book is the summary write up from the C/S Phase A study.
20 K LFI is the actively cooled LFI option (see LFI under instruments)

anisotropy power spectrum measurements for SCDM. MAP on top and COBRAS/SAMBA on the bottom.

anisotropy power spectrum measurements for SCDM and an open Universe CDM model. MAP on left and Planck on the right. The data points are an example of the signals expected with variations from cosmic variance and instrument noise included.
