PARAMETERS

amplitude_range = 10.0, 50.0
Range in percent of flux used for variable stars. The amplitudes are lineraly distributed within this range.
angle = 20.0
Angle in degrees of the semi-major-axis (always x!!!) of the moffat PSF-profile starting from right position and increasing counterclockwise.
angle_variation = 0.0
Variation in degrees of the angle of the semi-major-axis of the moffat PSF-profile. The angles are linearly distributed
from angle - angle_variation to angle + angle_variation.
cut-off = 0.99999
Moffat PSF-profile cut-off. Flux fraction wich is written to the image.
drop_range = 1.0, 5.0
Transit depth range in percent used for transiting planet host stars. The drop values are lineraly distributed within this range.
error = false
If true, for all simulated images errorframes (with no noise) are created.
fluxes = 0, 0, 0, 0, 0
Flux layers. For each of the 5 layers the fluxes of stars, variables and transiting planet host stars are exponential distibuted.
fwhm = 3.0, 3.1
Seeing full width half maximum. The first value refers to the axis pointing to the direction specified by angle.
fwhm_variation = 0.4, 0.1
Variation of seeing full width half maximum. The first value refers to the variation from one to another image taken in a different night. The second value refers to the variation from one to another image taken during the same night.
image_name = "stars_"
Output image filename prefix. For each entry in julian_day_list an image is created whose filename consists of this prefix followed by a number expressed in 5 digits (starting with "00001") and the suffix ".tbl".
table_name = "objects.tbl"
Output table name. In this table all informations (positions, fluxes, periods, amplitudes, etc.) are written.
