____________                                                                  
                                                                              
This PDS data archive contains data measured by XSM (X-ray Solar Monitor)     
instrument onboard Chandrayaan-1 spacecraft during NOP, i.e. between Nov      
2008 and Sep 2009. Only CODMAC level 2 data is included.                      
                                                                              
The directory structure of this data set is shown in Fig. 5 of XSM_EAICD      
Appendix 1.
