* Note 1: the values are defined by filters. The actual spectra may be cut off by detector edges.                
* Note 2: R1300 was retired in 2020 due to microcrack issue.                
* Note 3: VPH_J & VPH_H Grisms were replaced to LS_J and LS_H, respectively, in 2020.                 
* Note 4: You may also use NB/MB filters with grisms. Ask SA if necessary.

Update History:                        
2016-10-10: Default order-sorting filter for VPHJ is changed from OC_ZJ to HOLE+CSL. This mode has been effective since the October observations.                        
2016-11-15: The alias for VPH filters has changed to keep their consistency with grism name. e.g., DEF_VPHJ --> DEF_VPH_J etc.                        
2016-11-15: TheNB filters used with the VPH_H grism with the window imaging has changed from Fe2 to NB119, as the sky for Fe2 is too bright.                        
                         
2020-06-30: VPH-Y and R1300 Grisms were retired in 2020. Instead, LS_J and LS_H Grisms were installed in 2020. All the related aliases were updated.                        
2020-09-17: The filter for LS_J has changed from CSLM to OC_ZJ to suppress the ghost.                
                         
2023-2-5: VPH-Y is back, VPH-J/H are removed. A confusion on VPH_HK and VPH_K are cleared now.                
2023-02-05: The retirement of K-cont and ND were reflected to the table.                
                         
2024-03-05: removed remaining VPHJ/H part. Editted VPH_K part following the change of the definition. Added VB_K-related definition. Removed th BP-adding definition and put the note for it.
