Example 2 - Extracting a Scan Profile
 Using dsdlcurve
Run the task DSDLCURVE. This tool accumulates scanning data available
in the vicinity of a given object's position. Data is accumulated for
25 degrees of scan angle during times when the source is in the
experiment's field of view (FOV). Normally data is taken from the 1.5
x 3.0 degree FOV of the MED and HED3 detectors (raw scanning data file
dsdisk_15.raw), but data are also available for the 3.0 x 3.0 degree
FOV (raw scanning data file dsdisk_30.raw).

DEC in dd mm ss.s or degrees[] -73 42 21.8
Input file[] dsdisk_15.raw
Rootname for generated scan output:[] smcx1
Beta parameter:[0.6]
Weight data by daily efficiency ?[no]
Desired scan [1st scan = 0, 2nd scan = 1, 3rd scan = 2]:[0]
Options for setting up weights for discovery scalars :
0 use standard values for TOTAL RATE
1 use standard values for HARD RATE
2 use standard values for SOFT RATE
3 use standard values for R15 RATE
4 use standard values for WTD R15 RATE
5 use standard values for MED M1 RATE
6 to enter values from keyboard
IT IS STRONGLY ADVISED TO USE THE STANDARD VALUES
Discovery scalar weight option [0-6]:[] 3
.... Using standard weights for R15 rate
Use default detector (data) selection ?[yes]
Change anti-coincidence coefficient ?[no]

The discovery scalar modes changed throught the mission.
The following table gives the standard weights for
the 6 discovery scalar scanning modes. Each mode
possessed 8 different X-ray colors & anti-coincidence
coefficient, thus a total of 9 weights are available.

DAY RANGE when SRCE in FOV: 304.00 313.10 SCAN ANGLE: 293.53
The discovery scalar modes changed throught the mission:
Day GT 246.06 ; Mode = 2
Day GT 248.06 ; Mode = 3
Day GT 305.00 ; Mode = 4
Day GT 321.08 ; Mode = 5
Day GT 615.00 ; Mode = 6
Hence Mode for day range when srce in FOV = 4
