  We present X-ray imaging and spectral analysis of all microflares the Reuven
Ramaty High Energy Solar Spectroscopic Imager (RHESSI) observed between March
2002 and March 2007, a total of 25,705 events. These microflares are small
flares, from low GOES C Class to below A Class (background subtracted) and are
associated with active regions. They were found by searching the 6-12 keV
energy range during periods when the full sensitivity of RHESSI's detectors was
available (see paper I). Each microflare is automatically analyzed at the peak
time of the 6-12 keV emission: the thermal source size is found by
forward-fitting the complex visibilities for 4-8 keV, and the spectral
parameters (temperature, emission measure, power-law index) are found by
forward fitting a thermal plus non-thermal model. The combination of these
parameters allows us to present the first statistical analysis of the thermal
and non-thermal energy at the peak times of microflares.
