APPENDIX 1 - MCA166-USB spectral data format
The MiniMCA spectral data format is in compliance with the IAEA SPE Spectral Data Format (see SPEDAC PRO User’s Manual Rel. 1.0, IAEA, Feb 1994). All information is stored in a block structured ASCII BSA file so that its content can be viewed with any text editor and the file content can be printed directly.
Each block of the file is identified by a string that starts with the dollar sign ($) and ends with a colon (:). The block name is case sensitive. The structure of the data and the order in which blocks appear in the files is uniquely defined.
There are four general types of blocks used by the MiniMCA software (Release 1998):
1.Data Block
2.ROI information
3.Energy or Enrichment Calibration Data
4.Setup information
