Version History:

2-3:

• New Makefile and sfmakedepend. (Jeff Templon, 3/31) sfmakedepend is available at ~rom/bin, and also on www.
• Linux compatibility modifications from Jeff (3/31). The obviuosly safe ones were installed; the less safe ones were left in the new /linux directory (see README there). In a future patch the Makefile will allow easy Linux compilation.
• FPP code (Ed Brash, et.al., 4/26)
• First version of Aerogel code. (Ed Brash, 4/26)
• Treatment of helicity information. (EJB, 4/26) BCM and helicity merged in scaler_update, which needs to be rewritten (see notes in scaler_update) (RWM)
• Repairs to tracking and beam_vertex (Juncai Gao, 5/14) Big improvment in Ytarget, works for O16 experiment but beam_vertex needs to be rewritten for cryotarget.
• Improvements to coincidence time-of-flight. (Nilanga, 5/14)
• New DATABASE which contains optics (it is tied to new tracking, so don't mix old database with new code, etc). Database also contains Aerogel constants.
• First version of Lead-glass code. (Surik Mehrabyan, 5/15). Calibration and cluster-finding algorithms, some particle ID. If you don't have calibration file, it uses default constants. Some documentation is promised soon.

patch 1:

• Error in kinematic correction for hadron arm removed
• crashes occuring when scanning data in a loop (scan ... CHOPT=-l) have been resolved

2-2:

• New fpp software installed in espace.

2-1:

• target model 1 has been extended. It is now possible to have multiple foils. espace will
  determine in which foil scattering happened and investigate through which foils in- and
  out- going particles will pass. Energy loss in these foils is corrected for.
• Bug in routine beam_to_transport of the kinematics library fixed. This bug
  caused errors in the kinematic correction for extended targets.

2-0:

• espace and espace_sim (a special version to analyze AEEXB simulated data) have been combined
• CODA configuration file is extracted automatically from the data file unless the set/detmap-file
  command is issued.
• scaler information as stored by CODA has changed. Routine in espace updated but not
  compatible anymore with old data
• variables spec_e.x_det, spec_e.y_det, spec_e.th_det and spec_e.ph_det
  and spec_e.s1.x_scint, spec_e.s1.y_scint have been removed (where spec_e can be replaced by spec_h and s1 by s2 or s3).
  Instead use now spec_e.u1.x_det, spec_e.u1.y_det, spec_e.s1.x_det, etc.
• target thickness should be given in g/cm^2 (!!), however was interpreted in previous versions
  as being in mg/cm^2.

1-13:

• Bug (introduced in version 1-11) in calculating the 'Kinematic' momentum correction fixed.
• Bug in fitting the offsets (y000 and p000) in the focal plane vertex has been fixed.
• The covariance matrix of the focal plane vertex (due to errors in the measured drift time) is propagated to the target vertex
• Improved handling of different trigger types: "2-out-of-4" trigger is now analyzed correctly.
• Spectra of variables related to a spectrometer that is not being analyzed are now empty (as they should be).
• New installation procedure is implemented (thanks to Jeff Templon).

patch 6:

• OSF1 compatible

patch 3:

• New fpp routines.
• Bug in distance calculation routine dist_detector_vertex removed.
• Vertex covariance matrix contains multiple scattering contribution of spectrometer exit window.

1-12:

• Bug (introduced in version 1-11) when fitting the reconstructed vertex at the target is fixed.
• In the file, showing the results of tensor elements for the vertex reconstruction, a warning is given when the correlation between tensor coefficients is larger than 0.95.
• F-test is performed in multi-dim space when fitting the tensor coefficients. Those that fail the test are automatically removed.
• known problem: ESPACE is still not interpretting the "2-out-of-4" trigger correctly.

1-11:

• 'Kinematic' momentum corrections are now performed exactly, previous versions made only a first order approximation
• The alias file for PAW does not contain an entry for an NTUPLE (was useless).
• ESPACE and its libraries are now Sun Solaris compatible.

1-10:

• After a scan, a file is saved in which the information about the logicals imposed on the spectra are stored (thanks to Ed Brash and Dan Zainea)
• A bug in the variable TDC (introduced in version 1.9) has been removed.
• Preshower (ADC/TDC) and shower (ADC) spectra are now operational
