abspath | converts relative path to absolute path |

close_print | close the PS device opened with open_print and switch back to the previous device |

cxyouts | The CXYOUTS procedure draws text on the currently selected graphics device starting at the designated coordinate while supporting strings with color information. The string escapes the color information with "!f<color>", e.g. "foo!f100bar" draws "bar" with color 100. |

dms2deg | Convert coordinates in dms-Format to degrees |

explabel.pro | NO EXPLANATION |

file_exist | return 1 if filename exists, 0 if not |

floggen | Generate a logarithmic grid from xmin to xmax, each inclusive, with npt points |

gaussfold | Smoothes a plot by convolving with a Gaussian profile. Main purpose is to convolve a spectrum (flux against wavelength) with a given instrument resolution. Also applicable e.g. to smooth ligthcurves or in time-series analysis. |

hms2deg | Convert coordinates in hms-Format to degrees |

ifthen | This function returns a certain value if the expression is true, otherwise the other value. This function can be used as an "if statement in an expression" like the C ?: - operator. Other than the if statement this function works for arrays also provided the dimensions of expression and true/false values are the same. |

jwdateaxis | To plot an x-axis labeled with the date(s) instead of the Julian Date or MJD. |

jwlabelaxis | print axis labels at defined positions of the x- or y-axis (useful, e.g., for logarithmic axes spanning less than 2 decades) |

jwoploterr | Overplot data-points with possible uncertainties in the X- and Y-direction to a pre-existing plot (in this sense the functionality is similar to oploterr). If the error-bars do not fit in the given x- or y-range, plot arrows. |

jwplotlc | plot a lightcurve |

make_staircase | Calculate a "staircase" of x and y values from input x and y and associated dx and dy arrays. This allows nicer plotting than IDL's "histogram" symbol |

misclabel.pro | NO EXPLANATION |

PURPOSE: Procedure to set up plotting to ps-files CATEGORY: misc | NO EXPLANATION |

plotinter.pro | NO EXPLANATION |

ran2 | returns one or more uniform random deviate between 0.0 and 1.0 |

ran2_normal | returns one or more normally-distributed random numbers with mean of zero an standard deviation of one. |

ran2_poisson | returns one or more poisson-distributed random numbers with given mean, using the ran2 random number generator. |

ran3 | returns a uniform random deviate between 0.0 and 1.0 |

ran3_normal | returns one or more normally-distributed random numbers with mean of zero an standard deviation of one, using the ran3 random number generator. |

ran3_poisson | returns one or more poisson-distributed random numbers with given mean, using the ran3 random number generator. |

readoptima | Read optima binary data |

rndexp | return a random value on the basis of an exponential distribution with a given average |

rndexp2 | return a random value on the basis of an exponential distribution with a given average, based on ran2 |

strepex | Performs replacements of parts in strings by using regular expressions (REPlacement of regular EXpressions). Subexpressions may be also inserted into the replacement string. |
