MK_BSC makes BSC_INDEX and BSC_DATA structures from the BDA INDEX and DATA.
These structures contain instrumentally corrected BCS data for selected
channels and accumulation times. A typical run would look like:
IDL> mk_bsc,index,data,bsc_index,bsc_data,dp_sync=dp_sync
To analyze BCS data, you would begin by using YODAT to read the BDA
data file for the dates and times you are interested in. Yodat will return
a BDA index structure INDEX, a BDA data array DATA, and a structure DP_SYNC
which contains the DP synchronous data needed for deadtime corrections.
MK_BSC will prompt for various inputs such as start and stop times, channels to process, integration times, and which corrections (deadtime, crystal curvature, flux calibration) to apply. The DP_SYNC keyword is optional, but must be entered the first time if deadtime corrections are required. Subsequent calls to MK_BSC will use the last values of DP_SYNC data passed via this keyword.
The following keywords are also accepted:
The instrumentally corrected data will be output to a new set of structures BSC_INDEX and BSC_DATA. The data in BSC_DATA are stored as 256 element floating point arrays in fields with the following definitions:
Not all the above fields will be present. The fields that are present will depend on the corrections requested in MK_BSC. The actual data in each field array will occupy the first 0:NBINS-1 locations, where NBINS is the number of actual detector bins containing valid data. The value of NBINS is stored in BSC_INDEX.BSC.NBINS.
