• scheduleTol. This parameter specifies a tolerance (in minutes) for late start of an observation; an observation will be skipped if its scheduled time is more than scheduleTol minutes in the past.

• shortWait. This parameter specifies the length (in minutes) of certain short waiting periods during an observing run (such as the interval between successive checkings of the sun's altitude while the script waits for sunset).

• maxWait. This parameter specifies the time interval (in minutes) between successive slews toward the safe telescope position when the telescope tracks for an extended period of time without performing any observation. These slews are performed to prevent the telescope from accidentally tracking into some safety slew limit.

Bias frame parameters

' BIAS FRAME PARAMETERS
takeBias = True                       ' Set this to True if you wish to take bias frames          
nBias = 5                             ' Number of individual bias frames to be used in
                                      ' creating a master bias frame

• takeBias. Set this parameter to True if you wish to take bias frames (which is done by the script after sunset), otherwise set it to False.

• nBias. This parameter specifies the number of individual bias frames to take. After they are taken, these bias frames are median combined by the script into a master bias frame. Four versions of the master bias frame are produced:

  File name	Description
  MasterBias_bin1.fit	Full resolution (unbinned), full frame
  MasterBias_bin2.fit	2x2 binned, full frame
  MasterBias_bin1_center.fit	Full resolution (unbinned), center frame (covering the central 25% of the detector's area)
  MasterBias_bin2_center.fit	2x2 binned, center frame (covering the central 25% of the detector's area)

Dark frame parameters

' DARK FRAME PARAMETERS
takeDarks = True                      ' Set this to True if you wish to take darks after sunset   
nDarks = 5                            ' Number of individual dark frames to be used in
                                      ' creating a master dark
ExpTimeDark = 180.                    ' Dark frame exposure time (sec) 

• takeDarks. Set this parameter to True if you wish to take dark frames (which is done by the script after sunset, after taking bias frames), otherwise set it to False.

• nDarks. This parameter specifies the number of individual dark frames to take. After they are taken, these dark frames are median combined by the script into a master dark frame. Four versions of the master dark frame are produced:

  File name	Description
  MasterDark_bin1.fit	Full resolution (unbinned), full frame
  MasterDark_bin2.fit	2x2 binned, full frame
  MasterDark_bin1_center.fit	Full resolution (unbinned), center frame (covering the central 25% of the detector's area)
  MasterDark_bin2_center.fit	2x2 binned, center frame (covering the central 25% of the detector's area)

  The master dark frames produced by MU will need to be scaled when calibrating images whose exposure time is different from the dark frame's exposure time. Click here for details about the directories where dark frames are stored by the MU script.

• ExpTimeDark. This parameter specifies the exposure time (in seconds) for each individual dark frame.
