process_ccdlab()

curvit.process_ccdlab(output=None, time_list=None, XY_integers=None, XY_fractions=None, flat_list=None, framecount_per_sec=28.7185)

Generate a Curvit compatible events list from CCDLAB files.

Parameters:

  • output (file path) – The name of the output events list FITS file.

  • time_list (file path) – The name of the CCDLAB time list FITS file

  • XY_integers (file path) – The name of the CCDLAB XY integers FITS file

  • XY_fractions (file path) – The name of the CCDLAB XY fractions FITS file

  • flat_list (file path) – The name of the CCDLAB flat list FITS file

  • framecount_per_sec (float, optional) –

    The framerate of the observation, with a default value of 28.7185 frames per second for 512 x 512 window mode. The most accurate way to get the framerate would be to take the value of (1 / INT_TIME). INT_TIME value can be found from the corresponding image header. Approximate values of framerate for different window modes of UVIT are given in the table below.

    window mode

    frames per second

    512 x 512

    28.7

    350 x 350

    61

    300 x 300

    82

    250 x 250

    115

    180

    150 x 150

    300

    100 x 100

    640

Note

It is essential to set the correct value of the framerate. Most UVIT observations are carried out in 512 x 512 window mode.

Example

>>> import curvit
>>> process_ccdlab(output = 'output_events_list.fits',
...                time_list = 'sample_TimeList.fits',
...                XY_integers = 'sample_XYInts_List.fits',
...                XY_fractions = 'sample_XYFrac_List.fits',
...                flat_list = 'sample_FlatList.fits',
...                framecount_per_sec = 28.7185)

The above script will generate a FITS table called output_events_list.fits. You may then use it as input to curve or makecurves.
