Access through ICE:
To access and edit HJST parameter files, type one of the following into ICE command line. Exit parameter files with ':wq' to save or exit with ':q' to quit without saving.
Parameter Files:
-ice> epar obspars:
Contains parameters regarding file headings, filters, and focus.
exposure= Accepts float values. Sets maximum exposure time.
imagetyp= Accepts arguments such as 'object' or 'test'. Sets image type.
Note: Test frames will overwrite themselves and will not have a sequence number in their file name.
objectti= Accepts a string. Sets object title in file name.
sequenc= Accepts an integer. Sets sequence number.
Note: The next object will use the sequence number in the parameter file and the sequence number will increase by 1 upon complete integration. If an integration is aborted, the sequence number will NOT increase and may lead to errors if the incomplete file is not deleted from the tonight directory.
-ice> epar detpars:
Contains parameters that influence the detector and it's readout.
firstco= Accepts an integer between 1-2048. Defines the first column in the detector readout.
lastcol= Accepts an integer between 1-2048. Defines the last column in the detector readout.
firstro= Accepts an integer between 1-2048.Defines the first row in the detector readout.
lastrow= Accepts an integer between 1-2048. Defines the last row in the detector readout.
colbin= Accepts an integer between 1-16. Defines the column bin size.
rowbin= Accepts an integer between 1-16. Defines the row bin size.
-ice> epar empars:
Contains parameters regarding the use and configuration of the Exposure Meter.
emenabl= Accepts 'yes' and 'no'. Enables use of E-Meter.
emtotcn= Accepts integer values. Sets the maximum number of counts necessary to stop the integration.
Note: The integration will cease and readout will begin immediately after the target value is exceeded.
embinti= Accepts float values. Sets binning time in seconds.
Note: The shutter speed of the E-Meter sets a lower bound of .2 second binning time.
-ice> epar instrpars:
This file contains parameters that effect the TS2 instrument. It is typically left untouched because the parameters are read directly from the instrument into each .FITS file.
-ice> epar telpars:
Rarely used by observers, this file determines the heading of the .FITS files. Left alone, telpars will automatically populate date, time, weather, and seeing on every detector readout.
-ice> epar dmode:
The script 'dmode' returns 'detpars' parameters to their standard values. Each parameter within 'dmode' has a corresponding parameter within 'detpars' that it overwrites when called.
